Backend and API Engineers for a Fixed Stretch of Work

Backend engineers join for a set stretch. They build endpoints, fix a slow database or finish an integration in Node, NestJS, Laravel and PostgreSQL, then hand everything back with the documentation written and the tests passing.

What to hand over before they start

  • Repository access and a working README
  • Staging with realistic but invented data
  • API documents, or a list of callers
  • The schema, plus notes on fragile tables
  • One named person for daily questions

How the quality of their work is checked

Changes arrive as tested pull requests. Migrations run first on staging, are written to be reversible, and are read by your reviewer before they touch production data, which is where most backend damage happens. Endpoints carry request and response examples so a front-end developer can use them without asking anyone, and those examples stay in the repository beside the code. Slow queries are measured first. Guessing is not tuning.

When a backend engineer is not the answer

Some problems only look like backend work. A slow page may come from oversized images or a front end that makes too many calls, and a failing integration may be a dispute with the other party. Engineers can diagnose these. Diagnosis comes first, because a short investigation costs far less than building the wrong thing and discovering afterwards that the real fault lay elsewhere.

FAQ

Frequently asked questions

Which backend stacks can be covered?

Node with NestJS, Laravel and PostgreSQL. MySQL, Redis and queue systems come along with them, and if your stack is something else we say so before a contract, rather than learning it on your time.

Can the engineer work on live customer data?

Only when there is no alternative. Then it means the narrowest read access, a written reason, and a record of every query, while staging with masked or invented data stays the normal route. Production changes follow your release process.

What if our API has no documentation?

The engineer writes it first. Reading the code and the traffic logs comes before any new work, and the resulting documents also show you how far the existing code can be trusted. Plan time for that.

Do the engineers deploy to production?

Only if you want them to. Many clients keep deployment in-house and let the engineers prepare releases, and where engineers do deploy, they use your pipeline and a personal account.

What happens after you share your requirements

  1. A senior engineer reads your answers. Nobody phones first.
  2. Within one business day you get a written note: what we understood, what we would start with, and the questions we still have.
  3. If it fits, a proposal follows with the order of work, what we need from you and what you receive at each step.
  4. No call is booked and nothing is paid until you have read the note. Your details stay with us.
