About this gig

Have an AI startup idea but no technical co-founder? I'll build your MVP end-to-end a working product, not a prototype that breaks in front of users.


I'm an AI engineer with 4+ years of fullstack experience and 14+ production AI apps shipped, including an AI health coach, a Polymarket arbitrage trading platform, a Figma-style collaborative app with an embedded AI agent, an autonomous real estate agent built with LangGraph, and a computer vision system for property damage assessment.


I turn AI ideas into real products with auth, payments, AI features, and the infrastructure to run them.


What's included:

  • Product design & architecture
  • Auth and user accounts
  • Stripe billing & subscriptions
  • AI features (LLMs, RAG, agents, vision)
  • Clean, modern UI
  • Observability & evals (LangSmith / Langfuse)
  • Deployed on your domain
  • Source code & documentation


Tech stack: Next.js, TypeScript, Python, OpenAI / Anthropic, LangGraph, Postgres / pgvector / Neon, Stripe, AWS / GCP.


I ship products you can put in front of paying customers.

Message me with your idea and target users for a free scope breakdown.
