Backend & API Development
The reliable services and APIs the rest of the product runs on.
The engine room: the services, APIs, and data your product runs on.
What it is
We build the part of the system users never see but always feel — the services that hold your data, enforce your rules, and let your applications and partners talk to each other reliably.
Your app is slow, your data is inconsistent, or every new feature breaks something else. Usually that is not a front-end problem — it is the foundation underneath needing to be built or rebuilt properly.
What we build
APIs your systems can rely on
Documented, versioned interfaces your apps and partners can build against safely.
Data that stays correct
A structure that keeps information consistent as the product and the team grow.
Built to stay up
Tested behaviour, sensible limits, and monitoring so problems surface early.
Room to add
Structured so new capability slots in without unpicking what already works.
The retrieval, tool interfaces, queues, and data access that AI features need to work against real systems.
Where it fits
How we approach it
- Step 01
Model the data first
Get the structure right early; it is the expensive thing to change later.
- Step 02
Define the contract
Documented API behaviour agreed before the clients are built against it.
- Step 03
Instrument from the start
Logging, metrics, and alerts shipped alongside the service, not bolted on.
Scope, timeline, and team size are agreed per project. See how we work for the full delivery process.
Relevant technologies
Chosen per project against what you already run. This is what the work usually involves, not a fixed stack you have to adopt.
- Services
- REST and typed APIs, background jobs, queues, scheduled work
- Data
- Relational databases, schema migrations, caching, search indexes
- Reliability
- Automated tests, rate limiting, retries, structured logging and metrics
- Security
- Authentication, authorization, secret handling, audit trails
Example scenarios
Situations this service is built for. Illustrative examples of the kind of problem we solve — not named client engagements.
- 01For a product whose database was never designed for its current size — a data layer rebuilt before it fails.
- 02For a company whose partners want to integrate — a documented public API that is safe to expose.
- 03For a team where every release breaks something — services with real test coverage and clear boundaries.
