You will get a scalable backend API with database, auth and third-party integrations
Project details
Most backends demo well and fall over the first time real traffic hits them. The schema was guessed at, auth is half done, and one slow third-party call takes everything down.
I build backend APIs that hold up. Clean REST endpoints, a database schema that will not need rewriting in three months, real authentication with roles, and integrations that fail gracefully instead of silently.
You get versioned endpoints with validation, PostgreSQL or MongoDB models with migrations, JWT or OAuth auth, background jobs and queues for slow work, rate limiting, structured logging, and OpenAPI docs your frontend team can actually use.
Built with Node.js, Express or NestJS, Python, FastAPI or Django, PostgreSQL, Redis and Docker, deployed on your infrastructure with CI/CD. Tests cover the paths that matter, and you get documentation at handover so your team is not dependent on me.
Send me your endpoint list or product spec and I will tell you what the data model should look like before you pay anything.

━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHAT I BUILD
▸ Full web applications, end to end — React / Next.js front ends on Node, Django, or FastAPI
▸ Responsive, high-performance UIs — TypeScript, Tailwind, clean component architecture
▸ APIs & backends — REST and GraphQL, auth, payments, third-party integrations
▸ AI features that ship — chatbots, RAG pipelines, and AI agents grounded in your own data
▸ The production layer most freelancers skip — Docker, CI/CD, cloud deploy, monitoring
━━━━━━━━━━━━━━━━━━━━━━━━━━━
MY STACK
Frontend — React, Next.js (App Router), TypeScript, Tailwind CSS
Backend — Node.js, Express, NestJS, Python, Django, FastAPI
Databases — PostgreSQL, MongoDB, Redis
AI — OpenAI & Claude APIs, LangChain, RAG, vector DBs (pgvector, Pinecone)
DevOps — Docker, GitHub Actions, AWS, Vercel, CI/CD

HOW I WORK
1. A short call to pin down the outcome you need — not just the feature list
2. A written scope with milestones, so you know what lands and when
3. Working software early and often — you see progress weekly, not just at the end
4. Handover with documentation, so your team isn't dependent on me afterward

I take on a few projects at a time and reply fast — usually within a couple of hours. Send me your brief and I'll tell you honestly whether I'm the right fit.
