PROJECTS

PuzzleLove

A real-time multiplayer jigsaw puzzle and the whole platform around it, running on a single 8 GB VPS I operate: an authoritative Node + Socket.IO game server with a deterministic shared engine, a nightly PySpark + Delta Lake pipeline into a Postgres star-schema warehouse, a public Superset dashboard defined as code, and CI/CD that ships five images and rolls itself back on a failed health check.

Multi-Cloud Game Servers

Self-hosted Minecraft (Fabric) servers running on free-tier VMs across Oracle Cloud, AWS and Google Cloud, managed through a Pterodactyl panel with Wings running each game server in Docker. The panel runs on Ubuntu with Nginx and MySQL, Wings runs as a systemd service for automatic restarts, every host is locked down with cloud firewall rules, UFW, minimal open ports and key-based SSH, and backups go to S3 object storage automatically.
