Backend and API development in Birmingham
A tier-two automotive supplier in the Black Country answers to its customers' systems before its own. Schedules arrive by EDI, advance shipping notices go back the same way, portals demand their own uploads, and a missed message can hold up a line somewhere else. After the Jaguar Land Rover attack, those customers are also asking how their suppliers would recover if their own systems went down.
We build the backend that sits between your ERP and your customers: message handling that retries without duplicating, a record of every schedule and shipment notice sent and received, and alerts when something expected does not arrive. We work in Node and Python on PostgreSQL, keep the integration logic out of the ERP so it survives an upgrade, and document the recovery steps so they do not live only in one person's head.
Birmingham's software buyers are mostly not software companies. The city runs on financial and professional services: HSBC UK's head office at Centenary Square, the Birmingham office Goldman Sachs opened in 2021 with a technology focus, and the accountancy and law firms around Colmore Row and Snowhill. What they bring us is internal systems rather than consumer products: client portals, case and matter management, reporting that currently takes a week of spreadsheets, and integrations between platforms that different departments bought at different times.
Construction, transport and manufacturing make up the rest. HS2's Curzon Street terminus and the regeneration around it keep engineering consultancies, contractors and their supply chains busy, and those firms run on drawings, inspections, documents and project controls spread across too many tools. Manufacturing brings its own lesson. The 2025 cyber attack on Jaguar Land Rover stopped production at its West Midlands plants for weeks and reached deep into the supplier base, and suppliers now want business systems they can restore quickly and integrations that pick up cleanly when they come back.
The city has also watched its council's Oracle programme. The Register reports a forecast cost of £144.4 million against an original estimate of around £19 million, with the finance system still not working as intended. The lesson local buyers draw is the right one: customise less, test the money flows before go-live, and keep the people who use the system in the room. Hiring is competitive but cheaper than London, and the banks and professional firms compete for the same engineers. ITJobsWatch puts the median advertised salary for a software engineer in Birmingham at £70,000 over the six months to September 2026.
Working with us from Birmingham needs no adjustment on your side. Four hours of every working day overlap with yours, set across your morning, so stand-up and the decisions that follow happen live with the engineer who writes the code. The afternoon runs on written updates and pull requests in your own Slack, GitHub and Linear, with runbooks and architecture notes written as the work goes.
We are the right fit for a defined piece of work: an integration, a replacement for the spreadsheet, a portal with a deadline, or the groundwork before your own hire starts. We add senior capacity within days, begin with a fixed-price two-week piece so you can judge the output, and work white-label under your name for agencies.
Four ways this arrives.
We read the code, write down what it does versus what everyone believes it does, and give you the list of the five things most likely to page someone at night. Then we fix those first.
Usually queries, not architecture. We profile under real traffic, fix the plans and the indexes, and only then discuss whether anything needs splitting apart.
A mobile client, a partner integration, a public API. We design the contract first, version it properly, and write the docs your consumers will read.
Jobs that silently vanish, retries that duplicate charges, a queue nobody monitors. We make it idempotent, observable, and boring.
A moderated messaging backend where sends acknowledge in-band and the review runs behind them.

How do you work with teams in Birmingham?+
Four hours of every working day overlap with yours, set across your Birmingham morning, so stand-up and the day's decisions happen live. We join your calls and work in your tools: Slack, GitHub and Linear. You talk directly to the engineer who writes the code. The afternoon carries on in pull requests and written updates you can read when you are back at your desk, with runbooks and architecture notes written as we go.
Do you build for Birmingham law and accountancy firms?+
Yes. For the firms around Colmore Row and Snowhill we build client portals that work on a phone and ask for each piece of information once, matter and case management tools, and reports that assemble themselves instead of taking a week of spreadsheets. For accountancy practices we build AI features that pull figures from bank statements and receipts, suggest categories and put the result in front of an accountant to approve.
How does your rate compare to hiring in Birmingham?+
ITJobsWatch puts the median advertised salary for a software engineer in Birmingham at around £70,000. Our published rate is $35/hour with a $5,000 minimum engagement. There is no recruiting time and no employment overhead, and we can start within days of the first call. Most clients begin with a fixed-price two-week piece at $2,800, which lets you judge us on working software before committing to more.
Should we replace our ERP or build around it?+
Usually build around it, at least first. Birmingham has seen what heavy customisation can cost. Most of the pain sits in the gaps between an ERP and the rest of the business, and every customisation makes the ERP harder to upgrade. We build small tools alongside it that talk to it through supported interfaces. If replacement is genuinely the answer, we will say so and set out what to test before go-live.
Can you work in our existing codebase?+
Yes, and it is most of what we do. We do not require a rewrite as a condition of working with you. If we think a rewrite is genuinely the right call we will say so, with the reasoning and the cost, and you can decide.
What if the backend is in a language you do not list?+
Then we will tell you. We are useful in Node, Python and TypeScript. We can read Go and PHP well enough to migrate off them. We would not take a Rust or Elixir project and learn it on your budget.
Do you write tests?+
For anything with money, permissions or data loss in it, yes. We do not chase a coverage number. We will tell you which parts are covered and which are not in the handover notes.
Who owns the code?+
You do, from the first commit. Repositories live in your organisation. If we set them up, we transfer them before the first invoice.
What happens when the engagement ends?+
You get runbooks, architecture notes and a recorded walkthrough. We stay available for questions for a month at no cost, because a handover that needs us on retainer is not a handover.
