About

Started coding in 2023. Taught myself through YouTube, freeCodeCamp, and building projects until things clicked.

Now I do freelance work—mostly full-stack web apps and AI integrations. I focus on problems where AI can actually help, not just add complexity.

I work async and communicate clearly.

I can help with

  • Web apps from scratch (Next.js + FastAPI)
  • Adding AI to existing products
  • Deployment and infrastructure
