No junior benches, no staff augmentation, no lock-in. Scope and price agreed up front, production code every week, and a clean handover at the end.
Production code, not slideware
Working software running in a real environment from the first weeks, with a demo every week. You track progress against shipped code, not status decks.
Scope and price agreed up front
We scope the build with you and fix the price before we write production code. No open-ended hourly billing, no scope you discover on the invoice.
Senior engineers on your build
Principal engineers write the code. No juniors billed to your project, no account manager between you and the people shipping.
You own everything we write
Code, repository and IP are yours from day one. A clean handover with a runbook and docs — no lock-in, and no staff-augmentation contract to unwind.
Built to fit the systems you run
We integrate with the tools and data you already have and modernise legacy systems in steps, instead of pitching a rebuild-everything project you don't need.
Tested, documented, and handed over
Automated tests, load and edge cases covered, docs your team can run without us — plus an eval harness where AI is part of the build.
Four steps.Scoped to shipped.
From a thirty-minute scoping call to production software your team owns — milestones you sign off on, no surprises.
Thirty minutes with an engineer, then a written scope: what we build, the milestones, and a fixed price — all agreed before any production code.
Senior engineers ship working software to a real environment on a weekly cadence, with a demo every week. You see running code, not status reports.
Deployed, tested and documented — automated tests, load behaviour and edge cases covered, plus an eval harness where AI is part of the build.
Code, repository and runbook are yours. Month-to-month support if you want it — no lock-in, no staff-augmentation contract to unwind.
We're not for everyone.We're for the teams who need it shipped.
If any of these sound familiar, we should talk.
Founder without a technical team
An idea or a spec, and no one to build it
- No in-house engineers to ship it
- Agencies quoting open-ended hourly work
- Need it built right the first time
Outcome: A product built and shipped, and code you own.
Product or engineering lead
A roadmap bigger than the team
- More backlog than capacity
- A quality bar you can't drop
- Don't want to hire permanently for one push
Outcome: The build shipped to your standard, handed back clean.
Company on a legacy system
Software that's slowing the business down
- A codebase nobody wants to touch
- Manual work around the gaps
- Fear of a big-bang rewrite
Outcome: A modern system shipped in steps, not a risky rewrite.
Senior engineers. Fixed scope. You own the code.
What are custom software development services?
Custom software development services build software designed for one company's problem — web apps, mobile apps, and enterprise systems — instead of configuring an off-the-shelf tool to almost fit. At Unlocking Tech, senior engineers scope the build with you, ship working code every week, and hand over software you own. Scope and price are agreed up front, so 'custom' never means open-ended.
What do software engineering services include?
Our software engineering services cover the full build: architecture, development, testing, deployment and support. That includes web and mobile applications, SaaS products, integrations with the systems you already run, and modernising legacy software in steps. Everything is written to production standards by senior engineers, with automated tests and documentation, and you own the code at the end.
