About this gig

AI tools built you a prototype that breaks with real users? I build production-ready full stack SaaS & web apps that actually scale not demos.

I've built real software for years since before the AI era so I engineer the foundation right, then add AI on top.


What I build:

  • Full stack web apps & SaaS that handle real users & payments
  • AI in your app chatbots, AI agents, search & automation
  • Chatbots trained on your own docs & data
  • Voice & phone AI that answers calls & books appointments
  • AI that takes real actions in your app not just chat
  • Custom backends & databases built to scale
  • Mobile apps iOS, Android, cross-platform
  • Secure logins, user roles & Stripe payments
  • APIs & integrations that connect your tools
  • Rescue & rebuild broken AI-generated / vibe-coded apps
  • Production deployment & DevOps source code yours

I also build AI SaaS MVPs, fine-tune custom models, ship mobile apps, and rescue broken vibe-coded apps (Lovable, Cursor, Bolt, Replit).


Tech: JavaScript, TypeScript, React, Next.js, Node.js, Express, Python, FastAPI, MongoDB, PostgreSQL, Supabase, OpenAI, Claude, Gemini, LangChain, n8n, AWS, GCP, Docker, Kubernetes, CI/CD.

Building an AI product is easy. Making it succeed in production is hard. That is what I specialise in. Clients get complete AI systems built to last: AI agents, MCP servers, RAG pipelines, LLM fine-tuning on OpenAI, Claude, Gemini, Llama and open-source models, AI chatbots, AI voice agents, AI mobile apps, and full-stack SaaS platforms not demos. Not wrappers. Systems that real users actually use built and shipped for clients worldwide.Frontend, backend, AI, DevOps, bug fixing. One engineer, no handoffs.
