The part nobody sees and everybody depends on

The part nobody sees and everybody depends on: typed APIs, sane data models, and integrations that fail loudly.

API & Backend Development

Backends fail quietly. A frontend bug is on screen within minutes. A backend one shows up as a figure that was slightly wrong for three weeks, or an integration that stopped syncing and told nobody.

So we build them to fail loudly instead. Typed contracts, so a client cannot call an endpoint that no longer exists. Migrations reviewed like code. Integrations with retries and a dead-letter queue you can actually open. Load testing against the traffic shape you really get rather than a comfortable flat average.

Whether it is the backend for an app we are also building or an API a team you already have will consume, the deliverable includes the documentation and the generated client types.

What you get

  • REST or GraphQL APIs with generated client types
  • Schema design and migration strategy
  • Third-party integrations with retries and dead-letter handling
  • Load testing against your real traffic shape

Typical stack

  • Node.js
  • Python
  • PostgreSQL
  • Redis
Is this you

Signs you need this work

If more than one of these is true, this is usually the service that fixes it.

  • Your frontend and backend teams disagree about what an endpoint returns
  • Schema changes go out by hand and everybody holds their breath
  • An integration failed last month and you heard about it from a customer
  • The database has grown a column named something like data_2_final
  • Nobody has load tested, and your traffic is seasonal
How it runs

Four steps, in that order

The same sequence on every engagement, because each step is what makes the next one cheap.

  1. 01

    Scope

    We work out what you are actually trying to change, what the first release has to include, and what it does not. You leave with a written scope and a fixed price.

  2. 02

    Design

    Flows first, then screens for every state. You see the interface and can click through it before we write the code it would cost real money to change.

  3. 03

    Build

    Weekly builds on a live preview URL. You watch it come together instead of waiting for a reveal, and course corrections stay cheap.

  4. 04

    Deploy

    Pipeline, monitoring, and backups go up with the product. We stay on for the first weeks of real traffic, because that is when you learn what you actually built.

Questions

What clients ask before signing

REST or GraphQL?
REST for most things — simpler to cache, simpler to debug, simpler to hand to another team. GraphQL when clients genuinely need to shape their own queries, typically several different frontends against one data set. We will not sell you GraphQL because it looks good on a slide.
Can you work with our existing backend?
Yes, and a good share of this work is exactly that: taking something that grew organically and adding the types, tests, migrations, and monitoring it never got — without a rewrite. Rewrites are a last resort, and we will tell you plainly on the rare occasion one is genuinely the cheaper path.
Which database do you use?
PostgreSQL unless there is a specific reason not to. It handles relational data, JSON, and full-text search well enough that most projects never need a second store, with Redis for caching and queues when they are warranted.
How are secrets and production access handled?
Environment-scoped, never committed to the repository, with separate credentials per environment. Production access is limited to the people who need it and logged.
Will we be locked in to you?
No. Standard frameworks, documented decisions, and generated client types mean another team can pick it up. We would rather you stay because the work is good.
