Backend & API Development with Node.js and Python

APIs and services in Node.js (NestJS, Fastify, Express) or Python (FastAPI, Django), with clear REST or GraphQL contracts, Redis caching and background jobs for anything slow.

I write most backends in TypeScript on Node.js, so types flow from the database to the browser. NestJS suits larger APIs with many modules and a team that values structure; Fastify or Express suit smaller services where less framework is better.
