Forest BD Viewer

FEATURED

I wanted to explore how GIS data works at scale, so I built a full-stack app for querying and visualizing French forest biodiversity data (BD Forêt V2) across Île-de-France. Go backend serves spatial tiles via GraphQL; Next.js frontend renders multi-level Mapbox layers with polygon-based analysis.

Zoom-dependent layer switching: regions → departments → communes → forest types → cadastre parcels
Polygon analysis: area computation, forest coverage stats, TFV breakdown, top-8 species by hectare
Redis-cached MVT tile serving (24h/7d TTL) backed by PostGIS spatial queries
JWT auth-gated endpoints, context-based EN/FR i18n

Command Shell

Because apparently I can’t stop writing Go. A POSIX-compliant shell implemented from scratch — no standard library shortcuts for process management. Pipes, signals, job control, the works.

TVPlay

What if you could watch a movie… in your terminal? A CLI tool that renders video as ASCII art in real-time. Completely unnecessary. Completely fun.
