Bespoke software development in Sheffield.

• Sheffield or Leeds agency

  A company registered locally, on UK time all day, able to send someone to your site. You are buying proximity and a domestic invoice. The right call when the work needs people on a factory floor, runs through a procurement process that expects a nearby supplier, or is heavy on workshops.

• Contractor or staffing firm

  Individual engineers billed by the day into a process you already run, with your own lead still holding architecture, review and release. The right call when you already have an engineering manager with capacity to direct more people.

• Remote engineering partner

  A small senior team that owns a defined build, works your morning from outside the country and hands over the repository at the end. There is no UK entity, so the contract and the due-diligence paperwork have to be handled properly at the outset. The right call when you know what the system has to do and want it built properly the first time.

We are the third of those. Where one of the first two suits your organisation better, we say so on the first call rather than after a deposit changes hands.

• Hire a remote partner when

  • ✓Someone on your side can describe the process and make a decision about it without convening a working group.
  • ✓The work has a defined shape, a first release, a rebuild, or a set of modules, rather than an open-ended programme with a shifting sponsor.
  • ✓Six live hours a day are enough for what needs a conversation, and the rest can run on a written handover.
  • ✓You want the source code, the pipeline and the documentation held in your own organisation’s accounts once the work is finished.
  • ✓Personal or operational data is in scope in the ordinary way, and whoever owns compliance on your side is willing to set the rules and check our evidence against them.

• Hire locally instead when

  • ✓A framework agreement, a funding condition or a client’s own terms require a supplier established in the United Kingdom.
  • ✓People have to be physically present: a line changeover on a shop floor, a clinic go-live, hardware installed in a plant room.
  • ✓Your security policy forbids production access from outside the UK and the work cannot be done on masked data.
  • ✓Delivery genuinely has to run on UK time until early evening because the people who decide are only reachable late in the day.
  • ✓What you actually need is a contractor working under your own architect, in which case a staffing firm will cost less to manage.

• 01

  The rows we lose are worth reading first.

  A table where one column wins every row is a brochure. Two rows above are reasons to hire somebody else, and finding them here is cheaper than finding them in month four of a contract.

• 02

  Where data sits and where developers sit are two different questions.

  A UK-hosted system, in your own cloud account, can run with data never leaving the country while the engineers writing it work elsewhere under access controls your side has agreed. Most due-diligence conversations settle once that distinction is on the table.

• 03

  A staffing firm adds hands, not a system.

  Contract engineers are capacity for a process you already run. If nobody on your side is holding architecture, review and release quality, that capacity produces code faster than it produces a working system.

• 04

  Framework eligibility is binary.

  If a public-sector framework or a client flow-down requires a UK-established supplier, no amount of engineering quality changes that answer. Ask on the first call and it comes back the same day.

• Shop floor

  Manufacturing scheduling and quality systems

  Job scheduling, quality-tracking, non-conformance capture and supplier records for manufacturers supplying into aerospace and automotive programmes, usually replacing a whiteboard and a spreadsheet nobody trusts fully.

• Portals

  Patient, member and supplier portals

  A portal over the record system a clinic, a club or a supplier already runs, with role-scoped access, document handling and an audit trail that survives review. Often the fastest way to take routine work off a reception desk.

• SaaS

  SaaS products and first releases

  Multi-tenant products with billing, roles and usage limits for a founding team spinning a tool out of research at either of the city’s universities, shaped to reach paying users before the next funding conversation.

• Mobile

  Mobile apps for people away from a desk

  One Flutter codebase for iOS and Android, for field engineers, delivery drivers and coaching staff working sites where the signal is unreliable, built offline-first because that is where the work actually happens.

• Integrations

  Manufacturing, health and booking integrations

  Wiring a manufacturing execution system, a patient record or a booking platform to the tools around it, with queues, retries and a reconciliation view so a dropped message is seen rather than discovered weeks later.

• Cloud

  Cloud environments and release pipelines

  AWS accounts in your organisation’s name, defined as code, released in stages with monitoring and the change history a supplier review will ask you to produce.

1. Discovery and written scope

   One call about how the work moves today, who touches it and where it breaks, then a written scope with the exclusions named. The document is yours whatever you decide.

   A scope, a first-phase 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 operations lead argues with something real. Alongside them: the data model, access control, hosting region and rollback path, agreed in writing before an editor is opened.

   Approved screens, an architecture your technical lead has challenged, a data protection position your compliance lead has seen.

   1 to 2 weeks

3. Build in two-week slices

   Working software demonstrated every fortnight in your morning, against real records rather than dummy data. Each slice is checked against the scope while you are on the call, so progress is watched rather than reported.

   Working modules proven against real scenarios, and a backlog you have shaped as you went.

   6 to 14 weeks, by scope

4. Harden, then release

   Permissions, load behaviour, backups, monitoring and a rehearsed rollback signed off before anything reaches a Sheffield user. Where an audit trail is required, it is produced here rather than promised.

   A release your security reviewer can sign off, evidence attached rather than described.

   2 to 3 weeks

5. Run and extend

   Monitoring, a support window that follows UK office hours, and the next slice of roadmap chosen from what people actually use.

   A platform that keeps earning its place, and a team that hands it to yours whenever you ask.

   Monthly, 30 days notice

• First build

  Replacing the spreadsheet that runs the shop floor

  Scheduling, quality records and exceptions held together by a whiteboard, a spreadsheet and one person who knows the workarounds, rebuilt as a system with roles, approvals and a history of who did what. For operations and quality teams at manufacturers and engineering firms.

• Rebuild

  Retiring a system the vendor no longer supports

  An old desktop tool or an early web application rebuilt as a maintainable platform, without losing years of records or retraining a team over a weekend. For organisations whose core system has outlived its maker.

• Data protection

  Bringing a system up to UK GDPR properly

  Adding subject access tooling, retention enforcement, deletion that reaches backups and an audit trail that cannot be edited to a platform built before anyone asked for them. A supplier audit or a new compliance lead is usually the trigger. For teams facing a data protection review or a client audit.

• Extension

  Building around the system of record

  Portals, dashboards and custom modules layered on an ERP, a patient record system or a booking platform, so the core stays put and the retyping around it disappears. For organisations extending rather than replacing a core system.

• Advanced manufacturing and engineering

  Job scheduling, quality-tracking, non-conformance capture and supplier qualification for manufacturers connected to the Advanced Manufacturing Research Centre and the wider aerospace and automotive supply chain, where a fault has to be traced back through a batch, not just a part.

• Healthcare providers and NHS-linked services

  Referral pathways, scheduling and care-coordination tooling around an existing clinical system for providers working alongside Sheffield’s hospitals. Where patient data is in scope we build to UK GDPR and work under the rules your data protection lead sets, rather than promising a position on a web page.

• Higher education and research spin-outs

  Internal tools, data pipelines and the first commercial platform a research group builds when something it made for itself turns out to be worth selling, for teams around the University of Sheffield and Sheffield Hallam University.

• Sport, sports science and leisure

  Booking, membership and performance-tracking systems for sports facilities and sports-science organisations around the English Institute of Sport, where a session booked and a session actually delivered need to be the same record.

• Logistics and distribution along the M1 corridor

  Warehouse, dispatch and proof-of-delivery systems for operators moving goods through South Yorkshire, where the hard part is rarely one site but keeping a shipment in one consistent state across the systems that each think they own it.

• Professional and financial services

  Case management, client portals and reporting tooling for the accountancy, legal and financial-advice firms serving Sheffield’s manufacturing and healthcare base, where confidentiality and a clean audit trail are the actual product.

Not on the list? The opening question stays the same: what does a day of this work look like, and where does it break first?

1. 01

   UK GDPR and the Data Protection Act 2018

   Any Sheffield system holding personal data, whether that is patient records, employee data or customer information, sits under the UK General Data Protection Regulation and the Data Protection Act 2018, enforced by the Information Commissioner’s Office. The principles that reach the code are lawful basis, purpose limitation, data minimisation, storage limitation, integrity and confidentiality, and accountability, alongside the rights of access, rectification, erasure, restriction, portability and objection. The Data (Use and Access) Act 2025 amends parts of this regime in stages, so the position is re-verified before each publish. In practice that means a data inventory matching what the system actually stores, retention enforced by the system rather than remembered, deletion that reaches backups and exports, subject access answered from the system within the statutory period, and an audit trail that records who read a record as well as who changed it. Lawful basis and whether a data protection impact assessment is needed are decisions for your own data protection lead and counsel. What we build is the machinery that lets you act on the decisions they make. Sources: UK GDPR · Data Protection Act 2018 · Data (Use and Access) Act 2025 · Information Commissioner’s Office.

   Personal data

2. 02

   Quality and traceability evidence for manufacturing suppliers

   A supplier qualified into an aerospace or automotive programme is expected to produce traceable evidence: batch and lot tracking, non-conformance records, corrective-action history and supplier qualification files that can be pulled on request rather than assembled from memory during an audit. We build that evidence into the data model from the first sprint, versioned rather than editable in place, with a reason captured at the point a record changes. Certification and the standard your customer requires belong to your quality function, not to us. We build to produce the evidence your auditors ask for, and your team decides when the position is ready to submit. Sources: Customer-specific supplier quality requirements, verified per programme.

3. 03

   PCI DSS, kept out of your codebase

   The simplest way to handle card data is never to hold it. We tokenise at the payment provider, so the card number is captured by the provider’s own hosted field or SDK and your platform stores a token, the last four digits and a scheme. Your application never sees a primary account number, which keeps most of PCI DSS scope out of the code we write. Your PCI obligations stay with your organisation, and the self-assessment questionnaire depends on how you take payments. We build to keep the scope small and flag any requested feature that would widen it. Sources: PCI DSS v4.0.1 · PCI Security Standards Council.

   Payments

4. 04

   Supplier due-diligence questionnaires

   Manufacturers and healthcare providers in Sheffield increasingly send a supplier questionnaire before signing, particularly where their own customers run vendor-risk programmes. We complete it ourselves rather than sending a brochure, describing what we operate: named access with least privilege, review-gated change management, environment separation, logging and retention, tested restores, staged releases and a documented offboarding step. Where the honest answer is no, it is written as no with the compensating control next to it. Where your policy asks for a specific certification from the supplier itself, raise it on the first call and you will get our current position plainly, including where we fall short. 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 adding a compliance module to software that resists it. Where an audit finding or a client deadline is driving your timeline, that date is where we start planning backwards from.

1. 01

   The contract

   A master services agreement and statement of work governed by English law, with the jurisdiction, liability and termination clauses your counsel prefers. We never ask a Sheffield buyer to sign under Indian law, and we never run a project on an exchange of emails instead of a contract.

   English law

2. 02

   Currency, VAT and invoicing

   Invoices are raised in pounds sterling against the milestones or the monthly rate fixed in the contract. We are a supplier outside the UK, so VAT treatment is a matter for your accountant, and we provide whatever supplier details your finance team needs to record it correctly.

   GBP

3. 03

   Data protection terms

   Where we process personal data on your behalf we sign your processor terms, and any transfer position for a supplier in India is agreed with whoever holds data protection duties on your side before any data moves. Where the work can be done on masked or synthetic data instead, we say so, because it removes the question entirely.

   Article 28

4. 04

   Intellectual property

   Code, designs, documentation and infrastructure definitions are assigned to your organisation as they are created, not on final payment. Repositories, cloud accounts and domains are opened in your name from the first commit.

   Assignment

5. 05

   Confidentiality

   A mutual non-disclosure agreement, on your template or ours, is signed before anything confidential is shared. Nothing about your project is used as a reference without written permission.

   NDA

6. 06

   Insurance and vetting

   Certificates of insurance are provided on request, and due-diligence questionnaires are completed by the engineers who would do the work. Background checks on named engineers are arranged through your process where your policy requires them; raise it at contract stage rather than at kick-off.

   Due diligence

7. 07

   What the lack of a UK entity rules out

   There is no QalbIT entity in the United Kingdom, no Sheffield office and nobody we can send to your site on short notice. Where a framework agreement or a client’s own terms require a UK-established supplier or on-site delivery, we are simply not eligible, and we say so on the first call rather than after a proposal has gone out.

   The limit

None of that argues against a remote partner. It argues for handling the paperwork properly at the start, which is why we raise every item on this list before the estimate rather than after a signature.

• Backend and business rules

  • ✓Laravel on PHP 8 for modular business systems with a complete audit trail.
  • ✓Node.js and NestJS where integrations and event-driven flows dominate.
  • ✓Queues, schedulers and retries for syncs, alerts and end-of-shift reports.

• Interface

  • ✓React and Next.js, rendered on the server where search traffic counts.
  • ✓Keyboard-first data entry for scheduling and quality-tracking screens.
  • ✓Flutter for a single iOS and Android codebase that works offline first.

• Data and integration

  • ✓PostgreSQL and MySQL with constraints that protect record integrity.
  • ✓Append-only audit trails and versioned records where evidence is demanded.
  • ✓REST and GraphQL connections to ERPs, record systems and payment providers.

• Security and delivery

  • ✓AWS in your name, in a UK region, defined in Terraform.
  • ✓Logged least-privilege access, with any break-glass use reviewed after the fact.
  • ✓GitHub Actions pipelines with staged, reversible releases.

• A note on sourcing

  A note on sourcing

  You will not find market statistics on this page: nothing about Sheffield salaries, nothing about agency day rates, none of the failure-rate percentages that circulate without a primary source. Every number here is either ours or a case-study outcome, and each one says where it came from. Ask for the source if one of them matters to your decision, and we will send it or take the claim down.

1. 01

   The figures we can evidence

   We have delivered 120+ engagements for 50+ clients since 2018, hold a 5.0 on Clutch from 8 reviews and a 4.9 on Google from 18, and carry 100% job success on Upwork. Each of those can be checked on a public profile, which is why they are the only figures we put on a page.

2. 02

   Six live hours, the same clock as the rest of the UK

   09:00 to 15:00 UK time is inside our working day all year, which is 13:30 to 19:30 for us in summer and 14:30 to 20:30 in winter. Stand-ups, demos and decisions happen when you would hold them anyway, and a written handover goes out before we close.

3. 03

   We say what we are not

   No Sheffield office, no UK staff, no UK entity, and no implied presence anywhere on this site. The compliance and contract sections above exist because we would rather lose a deal at the scoping call than at a supplier audit.

4. 04

   The proposal names the people who build it

   We do not subcontract, and we do not move engineers off your project mid-sprint to cover somebody else’s account. The developers you interview are the developers whose names are on the commits.

5. 05

   We will tell you to hire locally

   Where a firm nearer to Sheffield is genuinely the better answer, you hear it on the first call. It costs us a project and saves you a year, which is why a fair share of our engagements arrive as referrals.
