Backend & APIs
The server-side systems behind your app: login, data storage, payments, and notifications, built to hold up as real users start using it daily.
In depth
What backend & apis really involves
The part of an app people see is the smaller half. Behind every login, order and notification sits a backend: the database, the rules, the sign-in system and the APIs the app talks to. When that layer is rushed, you feel it later as slow screens, data that doesn't match between devices, and features that take forever to add.
We start by modelling the data and the rules, because mistakes there are the hardest to undo. Who owns a record? What can change? What must be logged? Which actions need a permission check? From that comes an API with clear, versioned endpoints and documentation, so your mobile app, website and any future integration can share one foundation.
Running it matters as much as building it. Backups, monitoring, rate limits, careful handling of secrets, and a deploy process that doesn't cause downtime. We pick infrastructure that fits your size and budget, and we don't build for traffic you don't have yet, while leaving a clear route to grow.

How it goes
How we approach backend & apis
Model the data and permissions
We sketch the entities, how they relate and who can do what. This short exercise prevents the most expensive kind of rewrite.
Agree the API contract
Endpoints, request and response shapes and error formats are written down first, so frontend and backend can be built in parallel.
Build security in
Authentication, input checks, rate limiting and least-privilege access are part of the build, not a hardening phase tacked on at the end.
Deploy, monitor, back up
A repeatable deployment, logging, alerts and backups we've actually restored from, so we hear about problems before your customers do.
Ideal for
Who this fits
Apps with accounts, payments, or real-time data
Teams replacing a backend that can't scale
Watch out for
Common mistakes, and how we avoid them
An API shaped around one screen
It breaks the moment the design changes. We model the domain, so screens can change without a backend rewrite.
No versioning
Old app versions stay on phones for months. Versioned APIs let you improve the backend without breaking them.
Backups never tested
An untested backup is a hope. We check that restores really work.

Backend & APIs: common questions
Yes. We review what's there, note the gaps, and either extend it or put a cleaner API layer in front, depending on its condition.
