Custom Software Development
Systems built around how your business actually works.
- Working software in production within the first eight weeks
- Code, infrastructure and documentation you own outright
- Test coverage and CI so releases stop being an event
- A system your own team can extend after we hand over
Why companies bring us in
Off-the-shelf software forces your process into someone else's shape. When the gap starts costing more than the licence, a custom build pays for itself. Archanix designs, engineers and maintains software that fits the way your business already runs — and keeps fitting as it changes.

The work, itemised
Everything below is part of a software development engagement. We scope which parts you actually need before quoting.
Product discovery
Workshops that turn a backlog of requests into a scoped first release, with the features that do not earn their place cut before they cost anything.
Platform engineering
APIs, services and data models designed for the load you expect in three years, not just the pilot.
Internal tooling
Admin panels, dashboards and operations tools that replace the spreadsheets holding the business together.
SaaS products
Multi-tenant architecture, billing, role-based access and usage metering built in from the first release.
Legacy modernisation
Incremental migration off ageing systems with the old and new running side by side, so there is no big-bang cutover weekend.
Handover and support
Documentation, runbooks and paired sessions with your engineers, plus a support agreement if you would rather we kept running it.
How the engagement runs
Every stage ends with something you can read, click or decide on — never a status update alone.
- 01
Scope
A fixed-price discovery sprint produces the technical specification, architecture diagram and a release plan with real dates.
- 02
Design
Interface and data design together, reviewed with the people who will use the system daily before engineering starts.
- 03
Build
Two-week sprints against a shared board. Every sprint ends with something deployed you can click through.
- 04
Harden
Automated tests, load testing, security review and an accessibility pass before anything reaches production traffic.
- 05
Run
Monitoring, alerting and an agreed response window — plus a roadmap for what comes after launch.
What we build with
We pick tools for how long they will be maintainable, not for how new they are. Where you already have a stack, we work in it rather than arguing for a migration you did not ask for.
- TypeScript
- Node.js
- Next.js
- React
- Python
- Django
- .NET
- PostgreSQL
- MongoDB
- Redis
- Docker
- GitHub Actions
Software Development by industry
The same capability behaves differently depending on what the business does. These are the sectors where this service comes up most.
You do, in full, from the first commit. We work in your repository where possible, and every engagement ends with a complete handover of code, infrastructure definitions and documentation.
Frequently. We start with a paid code and infrastructure audit so both sides know the real state of it, then give you a fixed plan to finish or rebuild.
Discovery is always fixed-price. Delivery can be either — fixed-price when scope is genuinely settled, or a monthly retainer for a dedicated squad when it is still moving.
Short sprints, a visible board and a demo every two weeks. Scope changes are priced and agreed as they come up rather than absorbed silently until the deadline slips.
