Custom software development in California.

• California agency or studio

  In your time zone all day, in your office when needed, and contracting through a domestic entity. You are buying proximity and presence, and paying for both. The right answer when stakeholders are many, the scope is still forming, or a customer contract requires the work to be done in the United States.

• Contract staffing

  Individual engineers billed hourly into a process you already run. Architecture, code review, QA and release stay with your own engineering lead. The right answer when you have that lead and the bottleneck is hands, not direction.

• Remote engineering partner

  A named senior team that takes a written scope, owns architecture and delivery, works a fixed window of your morning from outside the country and hands over the repository at the end. No US entity, so the contract, the W-8BEN-E and the vendor questionnaire are handled at the start rather than discovered by finance.

We are the third. When the first or the second is the better fit for your project, the scoping reply says so, and we mean it.

• A remote partner works when

  • ✓The scope can be written down, and one person on your side can approve it without a committee.
  • ✓Two live hours between 08:00 and 10:00 Pacific are enough for decisions, and your team is comfortable working from written handovers for the rest of the day.
  • ✓The engagement is a defined build, a second product or a rebuild, rather than open-ended discovery with a sponsor who has not decided what they want.
  • ✓You want the code, the pipeline and the documentation in your own accounts from the first week, with no dependency on us to keep the lights on.
  • ✓Consumer data is in scope and your counsel or privacy lead will set the rules while we build the machinery that enforces them.

• Hire in California instead when

  • ✓A customer contract, a government grant or your own procurement policy requires a US-incorporated supplier or work performed on US soil.
  • ✓The work needs someone physically present: a clinical site, a studio floor, a warehouse cutover, a device on a bench.
  • ✓Your stakeholders can only meet in the afternoon, which for us is the middle of the night, and nobody can move the meeting.
  • ✓Your security policy prohibits access to production data from outside the country and the build cannot be done against masked data.
  • ✓You are really looking for staff augmentation under your own architect, which a contract firm will do with less overhead than we can.

• 01

  Two hours is the honest number.

  Other remote vendors write “overlapping hours” and leave you to discover what that means in November. Ours is 08:00 to 10:00 Pacific, held every working day, with everything else in writing. If your project needs more live contact than that, the California column is the right one.

• 02

  Where the software runs and where it is written are separate questions.

  Your product can run in AWS us-west-2 under your own account, with your own keys, while the engineers writing it sit in Gujarat. Most data-residency conversations end once that distinction is made, and most vendors leave it blurred.

• 03

  Staffing adds hands, not direction.

  Contract engineers make an existing process faster. If nobody on your side is holding architecture, review and release quality, more hands produce more code and not a better product.

• 04

  A US-only clause ends the conversation, and that is fine.

  If a customer agreement or a grant condition says the work must be performed in the United States, we are not eligible and we say so the same day. Ask on the first call so neither of us spends a week on a proposal.

• SaaS

  SaaS products, second products and first versions

  Multi-tenant applications with billing, plan limits, roles, SSO and an audit trail, for a company productising something it already runs internally or a funded team that needs a second product built without slowing the first.

• Platforms

  Internal platforms and operations systems

  The system that actually runs the company: intake, scheduling, approvals, exceptions and reporting, built around your process. It usually replaces a spreadsheet, a shared inbox and a no-code tool that stopped scaling.

• Mobile

  Consumer and field mobile apps

  One Flutter codebase for iOS and Android, built for App Store review from the first sprint, and offline-first when the users are crews and drivers a long way from a strong signal.

• Portals

  Customer, partner and vendor portals

  Self-service on top of the system you already own, with role-scoped access, document handling and a history of who did what, so your support queue stops answering questions the portal could.

• Integrations

  API and integration engineering

  Wiring a lab system, a rights database, a warehouse management platform, Stripe or a health record into one flow, with queues, retries and a reconciliation screen so a failed message is visible instead of silent.

• Cloud

  Cloud environments and release pipelines

  AWS accounts in your name in the region you choose, infrastructure as code, staged releases and monitoring, with the change history and access logs an enterprise customer’s security review will ask for.

1. Discovery and a written scope

   One call in the shared window to understand what the product has to do, who uses it and what it connects to, then a scope with the exclusions named and a price range attached. Nobody here estimates from a conversation, and the document is yours to keep.

   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 the first week so your product lead argues with something real, and alongside them the data model, tenancy, access control, hosting region and rollback path, written down before an editor is opened.

   Approved screens, an architecture your engineers can challenge, and a data-handling position your counsel has seen.

   1–2 weeks

3. Fortnightly releases

   Working software demoed live in your morning every two weeks and left running on a staging URL your team can open at 4 p.m. without us. Each release is checked against the scope in front of you.

   Working modules your users have tried, and a backlog you have shaped as you went.

   6–14 weeks, scope-dependent

4. Harden and ship

   Permissions, load, backups, monitoring and a rehearsed rollback signed off before a California user touches it. If an enterprise customer’s security review is coming, the evidence is produced here rather than promised.

   A release a security reviewer can accept, with the evidence attached.

   2–3 weeks

5. Run and extend

   Monitoring with alerts that reach us during our working day, a support window aligned to yours, and the next release chosen from what your users actually do rather than from the original plan.

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

   Monthly, 30 days notice

• Second product

  Building the next product without stalling the first

  Your engineers are busy keeping the revenue product alive. The new module, the partner portal or the internal tool gets built by a separate senior team on a written scope, in your repositories, on your standards. For funded SaaS and product companies with a full roadmap.

• First version

  A first version built to survive contact with users

  For a founding team in Los Angeles or San Diego that needs a working product for customers and investors: one platform, the core journey, and a codebase a future in-house team will not need to throw away. We built a vendor decision platform for CISOs this way, and it has run four years without a rewrite. For founders who want a first version, not a two-year platform.

• Rebuild

  Replacing software the company has outgrown

  A no-code stack, an early Firebase app or a legacy desktop tool rebuilt as a maintainable platform, without losing the data or retraining every user in a weekend. For companies whose tooling has become the bottleneck.

• Privacy retrofit

  Bringing an existing product up to CCPA and SOC 2 expectations

  Consent state, opt-out signal handling, data inventories, deletion that reaches exports and backups, audit logging and access reviews added to a product that was built before an enterprise customer or the state asked for them. For teams facing a customer security review or a privacy deadline.

1. 01

   Software and SaaS

   Second products, partner portals, billing and plan changes, admin consoles and the internal tooling a product company never finds time for. Tenancy, SSO, usage metering and an audit trail are the usual requirements, and enterprise customers will send a security questionnaire before they sign, so the evidence is designed in from the start.

2. 02

   Biotech and life sciences

   Sample tracking, study data, quality and batch records, supplier qualification and document workflows for teams in San Diego and the Bay Area whose systems fall under validation. Electronic records and signatures under 21 CFR Part 11 change the engineering: versioned records, an audit trail nobody can edit, reason-for-change capture and a qualification pack produced alongside the build.

3. 03

   Entertainment and media

   Rights and licensing databases, royalty calculation, content delivery workflows, talent and production scheduling, and the portals that let partners see their own statements. The recurring problem is one asset described differently in five systems, so a single record of the truth is usually where the work starts.

4. 04

   Logistics through the ports

   Importers, freight forwarders, drayage operators and distributors around the ports of Los Angeles and Long Beach and the Inland Empire warehouse belt: appointment scheduling, container tracking, proof of delivery, exception handling and inventory reconciled across sites. The hard part is keeping one shipment consistent across three systems that each think they own it.

5. 05

   Agriculture technology

   Field data capture, crop and yield tracking, labour scheduling, compliance records and grower portals for Central Valley operations, built offline-first because the signal in an orchard is not the user’s problem to solve.

6. 06

   Healthcare and digital health

   Scheduling, intake, care coordination and patient-facing apps around an existing record system. Where protected health information is involved we build to the HIPAA Security Rule safeguards and the Confidentiality of Medical Information Act, under rules your privacy officer sets rather than promises we make on a web page.

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

1. 01

   The CCPA as amended by the CPRA

   The California Consumer Privacy Act, amended by the California Privacy Rights Act, gives California residents rights to know what personal information a business holds, to delete it, to correct it, to opt out of its sale or sharing, and to limit the use of sensitive personal information. It applies to for-profit businesses doing business in California that meet one of its thresholds on revenue, on the number of consumers whose data is processed, or on the share of revenue earned from selling or sharing personal information. We print no threshold figures here on purpose; the revenue figure is adjusted over time and your counsel should read the current one. Two parts of the regime are engineering work rather than policy work. The first is honouring an opt-out preference signal such as Global Privacy Control, which has to reach your consent state, your analytics and every downstream tag and keep working after the next deployment. The second is deletion that actually deletes: from the primary store, from exports, from caches and from backups on a documented schedule. Rulemaking and administrative enforcement sit with the California Privacy Protection Agency, and the Attorney General enforces the Act as well. Whether your business is in scope, and which exemptions apply, is a question for your counsel. What we build is the machinery: a data inventory, consent state, an opt-out signal handler, request workflows with a clock on them, deletion paths that reach every copy, and retention rules a person can read.

   Consumer privacy

2. 02

   CalOPPA and the privacy policy your product has to publish

   The California Online Privacy Protection Act requires an operator of a commercial website or online service that collects personally identifiable information from California residents to post a conspicuous privacy policy describing what is collected, with whom it is shared, how a user can review and change it, and how the operator responds to Do Not Track signals. It reaches almost any consumer-facing product, well below the CCPA thresholds. The policy itself is your counsel’s document. Our part is making sure the product does what the policy says: the categories actually collected match the text, the sharing described is the sharing that happens, and the signal handling is real.

3. 03

   HIPAA safeguards and the Confidentiality of Medical Information Act

   Where a system 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. California adds the Confidentiality of Medical Information Act, which restricts disclosure of medical information by providers, health plans and certain businesses that handle it, and which reaches some digital health products that HIPAA does not. We do not promise a business associate agreement on a web page. Whether one is required, and what the CMIA adds for your product, is decided by your privacy officer and your counsel. We build to the safeguards and hand them the engineering evidence they need to sign the position off.

   Health data

4. 04

   21 CFR Part 11 for validated life-sciences systems

   For a biotech or pharmaceutical system holding records under Part 11, the controls are specific: validation for intended use, accurate and complete copies for inspection, a secure computer-generated audit trail that timestamps entries and changes without overwriting anything, authority checks on who may sign, and electronic signatures bound to their records. In practice records are versioned and never edited in place, reason-for-change is captured at the point of change, and the qualification evidence is written alongside the software rather than reconstructed at the end. Validation belongs to your quality function, not to your vendor. We build to the controls and write the specifications and test evidence in the form your QA team asks for; they decide when the system is qualified.

5. 05

   SOC 2 questionnaires from your enterprise customers

   A California SaaS company selling upmarket will be asked for SOC 2 evidence by its own customers, and it will ask the same of us. We answer with what we operate rather than with a brochure: named access with least privilege, change management through pull request and review, environment separation, logging and retention, backup and restore testing, 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. 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 say where we cannot meet the bar rather than let the questionnaire find it.

   Breach notification under Civil Code § 1798.82

   California requires a business that owns or licenses computerised personal information to notify affected California residents of a breach of the security of that data in the most expedient time possible and without unreasonable delay, and to notify the Attorney General when a single breach affects a large number of residents. The statute prescribes what the notice must contain. You cannot notify accurately unless the system can say which records were reached and by whom, so retained access logs, append-only audit trails, alerting on unusual access and a rehearsed procedure for reconstructing an incident are part of the build. A system that cannot answer that question turns a contained incident into a broad notification. The decision to notify, its timing and its wording belong to your counsel and your incident response plan. Our part is making the facts available quickly and reliably. Sources: Civil Code § 1798.82, California data breach notification statute · Office of the Attorney General.

   Incident duty

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

• 01

  The contract

  We sign your master services agreement under California law, with the venue, liability, termination and data-protection clauses your counsel prefers, and we do not ask clients to contract under Indian law. Engagements never run on an exchange of emails.

  Governing law

• 02

  Tax forms and invoices

  QalbIT is not a US entity, so a completed Form W-8BEN-E reaches your accounts payable team before the first invoice. Invoices are in US dollars against the milestones or the monthly rate written into the contract, with the purchase order reference your finance system needs.

  W-8BEN-E

• 03

  Intellectual property

  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.

  Assignment

• 04

  Confidentiality

  An NDA is in place before you share anything sensitive, yours or ours, and mutual is the normal case. Your name, product and project are never used as a reference without written agreement.

  NDA

• 05

  Security questionnaires and insurance

  The engineers who would do the work complete the questionnaire, and the answers describe what we actually run. Certificates of insurance are provided on request.

  Vendor risk

• 06

  Background checks

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

  On request

• 07

  No California presence, and what that rules out

  QalbIT has no United States entity, no California office and nobody who can be in your building on Thursday. Where a procurement rule, a grant condition or a customer flow-down requires a domestic supplier or work performed in the United States, we are not eligible, and you will hear that 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 instead of assuming it away, and we raise it before the estimate rather than after the contract.

• A note on sourcing

  A note on sourcing

  We quote no market figures on this page: no California salary bands, no agency rates, no failure statistics that circulate without a traceable primary source. The only numbers here are our own or our clients’, and each names where it comes from. If a figure matters to your decision, ask for the source and we will send it or withdraw the claim.

1. 01

   Shipping software since 2018

   120+ engagements 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. Those are the figures we can evidence, and they are the only ones we quote.

2. 02

   Honest about the Pacific offset

   Two live hours, 08:00 to 10:00 PT, every working day, with the rest of the day in writing. We would rather lose a project because that is not enough than win one by calling it “flexible overlap” and disappointing you in month two.

3. 03

   We say what we are

   No California office, no California staff, no United States entity, and no implied presence anywhere on this site. The compliance and paperwork sections exist so the security review has nothing left to discover.

4. 04

   Named engineers, no substitutions

   The people in the proposal write the code. Nothing is subcontracted, nobody is rotated to another account mid-sprint, and you can reach the founder without going through an account manager.

5. 05

   We will tell you to hire in-state

   When a firm in San Francisco, Los Angeles or San Diego is 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 work arrives as referrals.
