Custom software development in New York.

• New York agency

  Registered in the state, on Eastern time all day, able to put people in your office in Midtown or Hudson Yards. You are buying proximity, a domestic invoice and a vendor record nobody has to explain. Right when the work is stakeholder-heavy, needs hands on a trading floor or in a building, or has to pass a procurement rule that expects a New York supplier.

• Staffing firm

  Engineers billed by the hour into a process you already run. Architecture, code review, testing and release stay with your own head of engineering. Right when you have a technical leader with room to direct more people and no headcount to hire them.

• Remote engineering partner

  A small senior team that owns a defined build, works your morning from outside the country, and hands the repository over when it is done. No local entity, so the MSA, the W-8BEN-E and the vendor questionnaire have to be handled properly on day one. Right when you know what the system must do and want it built once, well.

We are the third. When one of the first two is the better answer, we say so on the scoping call rather than after a deposit.

• A remote partner is the right call when

  • ✓The system has a defined job and one person on your side can approve screens and decisions without convening a committee.
  • ✓The engagement is a build, a rebuild or a module on top of a platform you keep, not an open-ended programme with a sponsor who changes each quarter.
  • ✓Four live hours in your morning cover what needs a conversation, and the rest of your day can run from a written handover and a shared board.
  • ✓You want the source, the pipeline and the documentation in your own accounts at the end, not held hostage by a vendor.
  • ✓Regulated data is in scope and your compliance or security team is willing to set the rules and review the evidence we produce against them.

• Hire in New York instead when

  • ✓A client flow-down, a fund document, a grant or your own procurement policy requires a supplier incorporated in the United States or work performed there.
  • ✓People must be physically present: a trading-floor rollout, hardware in a building, a clinical go-live on the ward, a studio installation.
  • ✓Your security policy forbids any access to production data from outside the country and the work cannot be done against masked or synthetic data.
  • ✓The decisions are made in the afternoon by people who cannot move their diaries, so delivery has to run in one time zone all day.
  • ✓You really need extra hands under your own architect, in which case a staffing firm is cheaper to manage and easier to stop.

• 01

  Start with the rows we lose.

  A table where one column wins everything is an advertisement. Three rows above are reasons to hire someone else, and finding them here beats finding them in month four of a contract with no clean exit.

• 02

  Where the code runs and where the engineers sit are different questions.

  Your platform can live in a US region under your own AWS account while the people writing it sit in Ahmedabad. Most of a vendor-risk conversation is settled once that is written down, and many vendors blur it deliberately.

• 03

  A staffing firm adds capacity; a partner takes ownership.

  Contract engineers are hands inside a process you run. If nobody on your side holds architecture, review and release quality, more hands produce code faster than they produce a working system.

• 04

  A US-only clause is binary.

  If a fund document, a client flow-down or a grant requires the work to be performed in the United States, engineering quality does not substitute. Ask on the first call and you have the answer the same day.

• Operations

  Operations platforms for desks and back offices

  Onboarding, reconciliation, allocation, approvals, exceptions and reporting, built to the way your desk actually works rather than to a vendor template. Usually replacing three spreadsheets, a shared inbox and one analyst who knows the exceptions.

• Portals

  Investor, advertiser and tenant portals

  Self-service portals on top of the system you already own: statements and documents for investors, campaign performance for advertisers, requests, payments and building notices for tenants. Role-scoped, audited, and the fastest way to take volume off a service desk.

• SaaS

  SaaS products and first releases

  Multi-tenant products with billing, roles, usage limits and an audit trail, for a founding team in Flatiron or Dumbo that needs paying users before the next round, or for a company turning an internal tool into a product line.

• Mobile

  Apps for agents, couriers and building staff

  One Flutter codebase for iOS and Android, offline-first, because the signal on a subway platform or in a Midtown basement is not something your user should have to think about.

• Integrations

  Custodian, processor, ad-server and listing integrations

  Custodian and fund-admin feeds, payment processors, ad servers and DSPs, MLS and listing feeds, health records: connected through queues with retries and a reconciliation screen, so a failed message is visible rather than silently lost.

• Cloud

  Cloud environments in your name

  AWS accounts you own, infrastructure as code, staged releases and monitoring, with the access logs and change history a Part 500 third-party review or a hospital security office will ask you to produce.

1. Discovery and a written scope

   One call to walk through how work moves today, who touches it and where it breaks, then a written scope with the exclusions named. Nobody here estimates from a conversation, and the document is yours whether or not you hire us.

   A scope, a phase-one price range and the name of the engineer who would lead the build.

   48 hours

2. Prototype and architecture

   Clickable screens in week one, so your head of operations reacts to a prototype rather than a requirements document. Alongside it: the data model, entitlements, hosting region and rollback path, agreed in writing before anyone opens an editor.

   Approved screens, an architecture your CTO can read, and a data-handling position your compliance team has reviewed.

   1–2 weeks

3. Build in two-week slices

   Working software demoed every fortnight, live in your morning, against your real positions, campaigns or units rather than sample data. Each slice is checked against the scope in front of you, so progress is watched, not reported.

   Modules proven on real scenarios, and a backlog you have shaped as you went.

   6–14 weeks, scope-dependent

4. Harden and go live

   Permissions, load, backups, monitoring and a rehearsed rollback signed off before a user logs in. Where an audit trail, an access review or an examiner file is needed, it is produced here rather than promised.

   A release your security reviewer can accept, with the evidence attached rather than described.

   2–3 weeks

5. Operate and extend

   Monitoring, a support window on Eastern hours, and the next slice of roadmap chosen from what people actually use rather than from what was assumed in month one.

   A platform that keeps earning its place, and a team that can hand it to yours whenever you want it.

   Monthly, 30 days notice

• First build

  Retiring the spreadsheet that runs the desk

  Allocation, reconciliation or reporting held together by workbooks, a shared inbox and one analyst who knows the exceptions, rebuilt as a system with roles, approvals and a record of who did what and when. For operations and finance teams at funds, agencies and growing companies.

• Rebuild

  Replacing the platform nobody dares change

  An early web application, a vendor product with a thin API or an internal tool that predates the current team, rebuilt as a maintainable platform without losing years of data or retraining everyone over a weekend. For companies stuck on software the original developers have left behind.

• Evidence

  Bringing a system up to what the regulator now expects

  Adding audit trails, access reviews, MFA, retention rules and breach-scoping logs to a platform built before the SHIELD Act, Part 500 or a hospital security office asked for them. For teams facing a DFS certification, a security review or an audit finding.

• Extension

  Building around the core system instead of replacing it

  Portals, dashboards, mobile front ends and integrations on top of the portfolio system, ad server, property platform or record system you already run, so the system of record stays and the retyping around it goes. For companies extending a core platform they have no intention of ripping out.

1. 01

   Financial services and fintech

   Onboarding, reconciliation, allocation and reporting tooling for funds, advisers, lenders and payments companies in Manhattan. Entitlements, maker-checker rules, segregation of duties and a complete audit trail shape the build, and for DFS-regulated firms the software has to fit inside a Part 500 programme rather than sit beside it. Card data stays out of your code by tokenising at the processor.

2. 02

   Media, advertising and adtech

   Campaign and revenue reporting layers, rights and content management, and the integrations between ad servers, DSPs, CRMs and billing that agencies and publishers otherwise reconcile by hand each week. The hard part is rarely one feed. It is keeping a campaign in one state across four systems that each think they own it.

3. 03

   Hospital networks and provider groups

   Scheduling, intake, referral and care-coordination tooling around the record system a health network in the city or upstate already runs. Where protected health information is in scope we build to the HIPAA Security Rule safeguards and work under the rules your privacy officer sets rather than making promises on a web page.

4. 04

   Real estate and proptech

   Tenant and building-operations portals, leasing pipelines, maintenance requests, rent and fee handling, and the listing and MLS integrations behind them, for owners, managers and proptech products across the five boroughs and beyond. A lease has to stay consistent across the accounting system, the portal and the building staff app.

5. 05

   E-commerce and direct-to-consumer brands

   Order, inventory, returns and subscription tooling for brands that have outgrown their storefront platform’s built-in operations, plus the integrations to 3PLs, carriers and the payment processor. The storefront stays; the operations behind it become something a person can trust.

6. 06

   Startups and venture-backed products

   First releases for founding teams in Flatiron, Dumbo and Long Island City: one platform, the core journey, billing and an audit trail, delivered as a clickable prototype in week one and a working product in fortnightly slices. What raises money is a first version people pay for, not a two-year platform.

7. 07

   Professional services and the upstate corridor

   Client portals, matter and engagement tracking, time and billing tooling for law, accounting and consulting firms, and operations software for manufacturers and health systems from Albany to Rochester and Buffalo, all on the same Eastern-time overlap.

If your sector is not listed, the first question is the one we ask everyone: what does a day of this work look like, and where does it break?

1. 01

   The SHIELD Act: reasonable safeguards and breach notification

   All NY residents’ data. New York has no comprehensive consumer privacy statute in force that we can cite, so the state law that shapes most builds is the Stop Hacks and Improve Electronic Data Security Act, which amended General Business Law § 899-aa and added § 899-bb. Section 899-bb requires any person or business that holds private information of a New York resident to develop, implement and maintain reasonable administrative, technical and physical safeguards, and § 899-aa requires notice to affected residents and to the Attorney General, the Department of State and the State Police after a breach. The Act also widened “private information” to include biometric data and a username or email address together with a password or security question. For the software we write, the technical safeguards clause is a specification: risk assessment of the network and the software, detection and response to attacks and system failures, regular testing of key controls, and secure disposal of private information once it is no longer needed. The breach clause is a design constraint: you cannot notify accurately unless the system can say which records were reached and by whom, so retained access logs, an append-only audit trail and alerting on unusual access are part of the build rather than an add-on. Whether a given event is a breach under § 899-aa, and the timing and wording of any notice, belong to your counsel and your incident plan. Ours is to make the facts available quickly and reliably. Re-verify the Act against the Office of the Attorney General before relying on any detail here. Sources: Stop Hacks and Improve Electronic Data Security (SHIELD) Act, N.Y.

   23 NYCRR Part 500 for DFS-regulated firms

   Banks, insurers, licensed lenders. A bank, insurer, mortgage company, money transmitter or other entity licensed by the New York State Department of Financial Services is a covered entity under the Cybersecurity Regulation, 23 NYCRR Part 500, which was substantially amended in November 2023. The regulation requires a cybersecurity programme and written policy, a chief information security officer, an asset inventory, multi-factor authentication, annual penetration testing and regular vulnerability scanning, an incident response and business-continuity plan, notice to the Department within 72 hours of a qualifying cybersecurity event, and an annual certification of compliance signed by senior leadership. Two parts of Part 500 reach a vendor directly. Section 500.11 requires a written third-party service provider policy with due diligence and minimum contract practices, which is why your security questionnaire is thorough and why we answer it in full. And the programme itself expects the software you run to support MFA, access-privilege reviews, logging and encryption, so those are built in rather than promised for a later phase. Whether you are a covered entity, which class you fall in and how the programme is documented are questions for your CISO and counsel. We build the controls the regulation expects of the software and hand your CISO the engineering evidence for the certification file. Re-verify the current text and transition dates against the Department before relying on any detail here.

3. 03

   HIPAA technical safeguards for hospital networks

   Where a system for a New York hospital network, provider group or health plan touches protected health information, we build to the HIPAA Security Rule technical safeguards: unique user identification, automatic logoff, role-scoped access, encryption in transit and at rest, integrity controls, and an audit trail that records who read a record as well as who changed it. Minimum necessary is a data-model decision, so it is made at design time rather than argued about after go-live. We do not promise a business associate agreement on a web page. Whether one is required and what it must say is decided by your privacy officer and counsel. We build to the safeguards, work under your compliance team’s rules and hand them the engineering evidence they need to sign the position off.

   Health data

4. 04

   PCI DSS, kept out of your application

   The cheapest way to handle card data is never to hold it. We tokenise at the processor, so the card number is captured by the processor’s hosted field or SDK and your platform keeps a token, the last four digits and the brand. Your application never sees, transmits or stores a primary account number, which keeps most of PCI DSS scope out of the code we write for you. Your PCI obligations remain yours, and the right self-assessment questionnaire depends on how you take payments. We build to keep the scope small and say plainly when a requested feature would widen it. Sources: PCI DSS v4.0.1 · PCI Security Standards Council.

   Vendor security reviews mapped to SOC 2

   A New York fund, agency, hospital network or enterprise-selling startup will send a vendor security questionnaire mapped to the Trust Services Criteria before signing. We complete it ourselves rather than returning a brochure, and we answer with what we operate: named least-privilege access, change management through pull request and review, environment separation, logging and retention, tested backups, staged releases, incident handling and a documented offboarding step when an engineer rolls off. Where an answer is no, it is written as no with the compensating control beside it. A questionnaire padded with paragraphs is how a supplier drops off a shortlist late. If your policy requires an attestation report from the supplier itself, raise it at the first call. We will state our current position plainly, and where we cannot meet the bar we will say so before the questionnaire finds it. Sources: AICPA Trust Services Criteria for Security, Availability, Processing Integrity, Confidentiality and Privacy.

   Vendor risk

We build systems that produce this evidence natively rather than bolting a compliance module onto software that resists it. Where a certification date, an examiner visit or a security review is driving your timeline, that date is where we plan backwards from.

1. 01

   Whose MSA, whose law

   We sign your master services agreement under New York law, with the venue, liability, insurance and termination clauses your counsel wants. We do not ask clients to contract under the law of another country, and we do not run projects on an exchange of emails and a deposit.

   Contract

2. 02

   W-8BEN-E and invoicing

   We are a non-US entity, so a completed Form W-8BEN-E goes to your accounts payable team before the first invoice. Invoices are raised in US dollars against the milestones or the monthly rate in the contract, with the purchase order or engagement reference your finance system needs on them.

   Finance

3. 03

   Who owns the code

   Code, designs, documentation and infrastructure definitions are assigned to you as they are created, not on final payment. Repositories, cloud accounts and domains are opened in your name from the first commit, and every engineer on the account works under the same assignment and confidentiality terms.

   IP

4. 04

   Before you share anything

   A mutual NDA is in place first. Yours or ours, either is fine. Nothing about your project, your firm or your clients is used as a reference without written agreement.

   NDA

5. 05

   Insurance and questionnaires

   Certificates of insurance on request. Security questionnaires and third-party due-diligence packs are completed by the engineers who would do the work, not a sales desk, and the answers describe what we actually run.

   Vendor risk

6. 06

   Background checks on named engineers

   Where your policy, your fund documents or a client require background checks on the named engineers, we arrange them and return the results through your process. Raise it at contract stage rather than at kick-off, because it adds time before anyone can start.

   On request

7. 07

   What no local entity rules out

   QalbIT has no United States entity, no New York office and nobody who can be in your conference room on Thursday. Where a client flow-down, a fund document, a grant or a procurement rule requires a domestic supplier or work performed in the United States, we are not eligible, and you will hear it on the first call rather than after a proposal.

   The limit

None of this is a reason to avoid a remote partner. It is a reason to handle the paperwork properly at the start rather than assume it away, and we raise it before the estimate, not after the contract.

• A note on sourcing

  A note on sourcing

  We quote no market figures here: no salary bands, no local agency rates, no failure statistics that circulate without a traceable source. The only numbers on this page are our own, and each names where it comes from. For a worked example, see CyberFind, a B2B SaaS we built and still run: a vendor-intelligence platform on Next.js, Node.js and PostgreSQL, four years in production with no rewrite, now carrying 500+ verified CISOs and 2,000+ peer reviews. Ask for the source behind any figure and we will send it or withdraw the claim.

1. 01

   A record we can show, not describe

   120+ engagements delivered for 50+ clients since 2018, across web, mobile and platform work. Clutch 5.0 from 8 reviews, Google 4.9 from 18 reviews, and 100% job success on Upwork. Four figures, each with a public profile behind it, and the four we quote.

2. 02

   Your morning is our meeting time

   Four live hours every working day, 08:00 to 12:00 ET, in our evening in Ahmedabad. Calls, demos and decisions happen in that window, and the written handover reaches you before we log off, so nothing waits on a status meeting.

3. 03

   No pretence of a New York office

   No New York office, no New York staff, no US entity and no implied presence anywhere on this site. The compliance and paperwork sections exist because we would rather lose a deal on the scoping call than in the vendor-risk review.

4. 04

   The engineers in the proposal build it

   Whoever is named in the scope writes the code. Nothing is handed to another firm, nobody is quietly swapped mid-sprint to cover another account, and you can reach the founder without going through an account manager.

5. 05

   We will point you at a Manhattan firm when that is right

   When an agency in the city is genuinely the better answer, you hear it on the first call. It costs us a project and saves you a year, and it is why a fair share of our engagements arrive as referrals.
