Independent builder

Hi, I'm raytracer.

I turn ideas into shipped web products — 3D e-commerce, AI-assisted manufacturing, and hackathon discovery.

About

What I do.

I'm an independent builder who takes products from idea to live on the web. I enjoy working across the whole stack — 3D rendering in the browser, AI-assisted workflows, payments and e-commerce, and scraping data from messy sources into something useful.

  • Full-stack web
  • 3D & WebGL
  • AI integrations
  • E-commerce & payments
  • Scraping & aggregation
  • Shipping fast
