## Projects
- TortoiseLang (slowlang): Satirical programming language and IDE that throttles execution when you type too fast — then triggers ASCII turtle rage and poetic haiku feedback. (https://github.com/sebin-gg/slowlang)
- Event Tracker: Full-stack event management for the FOCES Volunteer Project. Pydantic-validated API, search indexing, SQLite persistence, responsive dark/light UI. Live on GitHub Pages. (https://github.com/sebin-gg/Event-Tracker)
- Kindred: Platform where volunteers log impact across six tracks, earn titles and appear in a private dashboard. Rate-limited REST API with bcrypt auth. (https://github.com/sebin-gg/kindred)
- Aegis: Streaming terminal logs, automated attack simulation, iptables mitigation commands and optional local-AI analysis via Ollama. (https://github.com/sebin-gg/Aegis)
- brevity-prompt: Compresses prompts in-browser before they hit ChatGPT, Claude or Gemini — 40–65% fewer tokens. Pure client-side regex, zero external dependencies. (https://github.com/sebin-gg/brevity-prompt)
- ShyUI: Lightweight Windows tray app that auto-hides the title bar of maximized windows for a cleaner fullscreen-style view. Single C# file on the Win32 API with per-app control and global hotkeys. (https://github.com/sebin-gg/shyui)
