Backend development with Node.js, NestJS and GraphQL

A booking confirmation that arrives, a price that is always right, a login that works on the first try: all of that is backend work. When it is done well nobody notices. When it is done badly, customers call you instead of buying.

We design the data model around how your business actually operates, write the API in Node.js with NestJS or Express, and connect it to PostgreSQL and the services you already pay for. Everything is versioned, tested and documented, so the next developer can continue without us.

Before we write a line of backend code we map the real processes: who creates an order, who approves it, what happens when a payment fails, which systems must be told. That map becomes the data model and the API contract, which we agree with you in writing. Then we build in small vertical slices, each one usable on a staging environment, so you see working software every week instead of a demo at the end. Authentication, permissions, backups and audit logs are built in from the first slice, because retrofitting them is where projects go over budget.
