Code Hunterz

API and Backend Engineering

We design and build the backend: the data, the API, and the jobs behind the request, documented so another developer can continue.

The problem

Front ends multiply and the server becomes a set of one-off endpoints. Permissions get fuzzy. A report no longer matches what the app shows, because each client computed the rule itself.

We put the rules in one place. Clients call an API. Background work runs in jobs you can retry. Integrations are explicit, not hidden in a controller someone is afraid to touch.

What you get

Domain model

The entities and the rules, written so product and engineering mean the same thing.

API

Authenticated endpoints for the clients you have, with errors that a UI can show.

Jobs

Email, imports, and other work that should not block the request.

Notes

How to run it locally and what each integration expects.

How the work runs

  1. 01

    Name the source of truth

    Which system owns the customer, the order, or the document.

  2. 02

    Design the contract

    Resources, auth, and the errors, reviewed before a large implementation.

  3. 03

    Implement

    The API and the data migrations needed to get there.

  4. 04

    Exercise it

    A client, even a small one, proves the contract. A PDF of endpoints does not.

Stack

  • Node.js or the stack your system already uses
  • Postgres
  • REST or GraphQL where it earns its keep
  • Queues for background work

Who it is for

  • Teams whose mobile and web apps disagree
  • Companies adding a partner or public API
  • Products about to add automation that needs a stable contract

Reviews

Questions

REST or GraphQL?

REST unless you have many clients that need very different slices of the same graph. We will not introduce GraphQL for a single web app without a reason.

Can you work in our repository?

Yes. We would rather extend a backend you can run than drop a second service beside it.

Do you write the infrastructure too?

Deploy, environments, and monitoring are the Cloud and DevOps service. We coordinate them. They are not silently included.

How do you handle auth?

With the identity system you already have when it is sound. We do not add a second login without a reason.

Cloud and DevOps

Environments, CI, and monitoring so a release is a known step instead of a personal ritual.

SaaS MVP Development

A first version people can sign up for and pay for: accounts, the core workflow, and billing.

AI Integration

Model-backed features added to software you already run, with your data and your permissions.
