Addis Ababa, Ethiopia - 1:00 am local time
I am Full-Stack Developer building AI SaaS MVPs in Next.js, React and Node.js. From empty repo to deployed: frontend, backend, database, API integration, and AI that survives real users.
Your AI feature works in the demo. Then a real user touches it and it falls over.
Or the MVP that was six weeks out is now four months late. Or the API between two systems breaks every time one of them changes.
Here's what usually goes wrong. Most developers can wire up an OpenAI call. Far fewer build the backend that survives one: retries when the API times out, caching so you're not paying twice for the same answer, a schema that doesn't need rewriting the moment you add a second feature. That gap is where MVPs die, and it's the part I actually care about.
WHAT I BUILD AS A FULL-STACK DEVELOPER
"WE NEED AN MVP IN WEEKS, NOT MONTHS."
Next.js App Router, React, Node.js, Supabase with Row-Level Security, auth with roles, multi-tenant ready. I've shipped this stack enough times that the boring 60% goes fast, which leaves real time for the part that's actually yours. Full stack means full stack here: frontend, backend, database, deploy. You get a working product at every milestone, not a big reveal at the end.
"THESE TWO SYSTEMS DON'T TALK TO EACH OTHER." — API INTEGRATION
API integration is most of real product work. Stripe billing, third-party REST APIs, webhooks, OAuth, and the error handling nobody writes until it breaks in production. I've built payment integration, marketplace deployment and custom API layers on live client products, in React and Node.js.
"OUR CHATBOT MAKES THINGS UP."
Generic LLM output isn't a prompt problem, it's a retrieval problem. I build RAG systems that answer from your documents, your data, using vector search on Supabase pgvector so every response is grounded in something real. Built exactly this for a coaching platform: GPT-4 answering from the client's proprietary framework instead of guessing, with citations back to the source.
"OUR BACKEND IS SLOW AND WE DON'T KNOW WHY."
Usually queries, sometimes caching, occasionally architecture. I cut backend latency 60% through PostgreSQL query optimization and Redis caching across Node.js services. If your Next.js app is slow, I'll find out why before I start rewriting things.
HOW I WORK
Scope before I build, so you know what's in version one and what waits.
Working product at every milestone, not a reveal at the end.
I write the code myself. No team behind me, no mystery contractor.
You get the keys: README, deploy pipeline, env setup. Nothing you can't hand off.

So: building an AI SaaS MVP in Next.js, adding an API integration to a React app you already have, or fixing a Next.js and Node.js build that isn't holding up? Tell me what's going on. I'll tell you straight how I'd approach it and roughly what it takes. If I'm not the right person, I'll say that too.
