About this gig

Greetings!

Need a modern, scalable web app with builtin AI? I design and develop production ready fullstack applications powered by Next.js (frontend) and FastAPI (backend), with secure auth, clean APIs, and optional AI features like ChatGPT chatbots, RAG, and realtime voice.


What youll get:

- Fullstack architecture: Next.js (App Router), React, TypeScript (optional), FastAPI REST.

- AI features: OpenAI/LangChain chatbots, RAG with vector DB (Pinecone/Supabase), prompt design, tools/functions.

- Realtime & voice: WebSockets/Server Actions, Twilio/WebRTC, streaming TTS/STT.

- Data layer: Supabase/Postgres or MongoDB, Prisma/SQLAlchemy, schema/migrations.

- Auth & security: JWT/NextAuth, RBAC, ratelimits, input validation.

- Quality & performance: Lighthouse/CLS/Web Vitals, caching, edge/CDN, lazy/memoization.

- DX & delivery: GitHub repo, clear commits, env templates, README, API docs, Postman collection.

- Deployment: Vercel/Fly.io/Render/Supabaseconfigured and ready.


Process:

1) Brief and wireframe

2) Schema & API design

3) Iterative build with weekly demos

4) QA/perf pass

5) Deploy + handover.
