JavaScript/TypeScript, React, Node.js, Python. Supabase and Postgres. More of a generalist — I ship the whole thing: frontend, backend, deploy, and the SEO nobody wants to do.

Technical SEO for JS-heavy apps — mostly by finding out what my own prerender was quietly leaving out. Also getting deeper into Supabase RLS and image generation with Python/Pillow.

tarot-magic.com — a tarot site in 4 languages (312 card pages, weekly long-form articles). Plus utilixi.com, a set of small browser tools. Side quest: automating social content with Python.

Happy to talk about React + Supabase, multilingual sites (hreflang, per-locale content), or why your SPA ranks worse than it should. Always up for a second pair of eyes on someone's SEO audit.
