🌸 Crafting automations that work while the world sleeps 🌙

Portfolio ZelligeDB

✿ About Me

  • 💻 Software developer building real-world products — automation, AI-powered tools, static analysis, and computer-vision systems.
  • 🧩 Just shipped ZelligeDB: a full SQL database engine built from scratch in Rust — pages, B+Tree, crash-proof WAL, MVCC, SQL, and a Postgres-compatible server. Try it in the browser ↗.
  • 🩺 Also just shipped RepoDoctor: a GitHub repository analyzer with a zero-dependency static-analysis engine — complexity metrics, secret & CVE detection, architecture graphs.
  • 🌷 Weakness for clean code, tested APIs, and anything that runs on autopilot.
