Forest BD Viewer

FEATURED

A full-stack geospatial platform demonstrating end-to-end systems thinking: concurrent LiDAR data fetching with goroutines, PostGIS spatial queries at scale, and MVT tile rendering optimization. Built to explore real-world performance challenges in distributed GIS systems processing French forest biodiversity data (BD Forêt V2) across Île-de-France.

  • Concurrent data fetching with goroutine pools and backpressure handling
  • PostGIS spatial queries: polygon analysis, area computation, forest coverage stats
  • Redis-cached MVT tile serving (24h TTL) for sub-100ms response times
  • Zoom-dependent layer switching (regions → departments → communes → forest types)
  • JWT auth-gated endpoints, context-based EN/FR i18n
  • Full Docker Compose stack for reproducible deployments

Command Shell

A POSIX-compliant shell built from scratch in Go—no standard library shortcuts for process management. This project demonstrates deep OS understanding: fork/exec/wait, process groups, signal handling, and job control. The kind of low-level systems thinking that's foundational to understanding containers, orchestration, and systems reliability.

  • Raw system calls (fork, execve, wait) for process management
  • Signal handling (SIGINT, SIGTSTP) and job control
  • Pipe handling and I/O redirection
  • Background execution and process groups

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.

  • FFmpeg bindings for frame extraction
  • Optimized terminal cursor manipulation for smooth playback
