I will build your backend rest API with nodejs and typescript


About this gig
Senior full-stack developer with 10+ years of experience. I build backend APIs and services in Node.js and TypeScript, both new and on existing codebases, for direct clients and agency projects on tight deadlines.
I build the backend properly: a REST API on Express or Fastify, TypeScript throughout, PostgreSQL or MySQL with migrations, authentication with JWT or OAuth, input validation, error handling, automated tests, and a README your team can follow. Optional Dockerised deployment and a CI pipeline.
You get a clean, documented codebase, not a prototype you have to rewrite later.
Also: third-party API integrations, webhooks, queues and background jobs, and OpenAI/LLM endpoints.
Stack: Node.js, TypeScript, Express, Fastify, NestJS, AdonisJS, PostgreSQL, MySQL, Redis, Docker.
Message me before ordering so we can agree on scope. I'll point you to the right package or send a custom offer for larger work.
Happy to work without ANY generative AI if you prefer, I already keep its usage limited anyway; it would just add a little to the timeline.

FAQ
Can you work with our existing API?
Yes - extending or fixing an existing Node backend is fine, send me the repo.
Which database?
PostgreSQL by default; MySQL, SQLite or MongoDB on request.
Do you build the frontend too?
That's a separate gig - see my Vue 3 gig, or ask for a bundled custom offer.
