About this gig

I'm a full-stack developer with 5+ years building and shipping production SaaS apps clean, fast, and built to scale.

What I'll build for you:

  • Next.js / React + TypeScript frontend (responsive, not a template)
  • Node.js backend, REST APIs & database (Supabase/Postgres or MongoDB)
  • Secure auth + role-based access
  • Stripe / payment integration (checkout, subscriptions, webhooks)
  • AI features that actually work chatbots, RAG, LLM automation (OpenAI/Anthropic) with reliable structured output
  • Deployment (Vercel) + clean docs & handover

Why me:

  • Real shipped SaaS products, not just demos
  • AI baked into the core, not bolted on
  • Clean, maintainable code your team can extend
  • Clear communication, milestone delivery, no black boxes

Whether it's an MVP, an AI tool, or a full SaaS let's turn your idea into a working product.

Message me before ordering so I can scope your project and give you an accurate plan.

I build production web apps with AI. Over ~5 years I've shipped SaaS products end to end: Next.js/React + TypeScript front ends, Node.js/Express APIs, Postgres/MongoDB schemas, Stripe/subscription billing, auth. On the AI side I've built RAG pipelines, vector search (Pinecone/LangChain), and structured-output LLM features with schema validation and retries — including an intent-routing chat layer that decides whether to run an action or answer from retrieval. Recent work includes a graph-based research tool and a Next.js + Supabase SaaS with AI processing and subscription billing.
