About this gig

Need the backend for your MVP built so you can keep growing on it? BYD Tech builds it in Node.js or Python.


We build the API, auth, database and deployment: NestJS or Express on Node.js, or FastAPI on Python, with PostgreSQL, deployed to AWS. Clean structure, tests on the parts that matter, and API docs your next developer can read.


What you get:

- REST API with authentication and roles

- PostgreSQL schema and migrations

- Swagger/OpenAPI documentation

- AWS deployment and a CI pipeline (higher packages)

- Code in your GitHub, with a README


How it works: send your feature list, even a rough one. We confirm scope and what's included in chat before starting. An engineer reviews every AI-assisted change before it reaches you.


Need a front end too? The Premium package includes a React or Next.js web app.

We are a small engineering studio that builds MVPs, AI agents, and web and mobile apps. We build production AI: LLM agents with tool calling, RAG over your own documents, evaluation harnesses that catch regressions before they ship, and guardrails that stop a model inventing things. On the backend, Node.js, NestJS, Python and FastAPI on AWS and Azure. Your code lives in your GitHub from day one, and every AI-assisted change is reviewed by an engineer before it reaches you. Tell us what you're building and we'll tell you honestly whether we're a fit.
