Here are a few things I’ve built: apps, tools, websites, and experiments.
Minimal, drift-free EMOM and Tabata interval timer for Android, with full-screen phase colors legible mid-effort and self-updating release channels outside Google Play.
Portable development toolkit for isolated environments, reusable agent workflows, capability-based installation, and controlled automation across a Linux workstation.
Terminal algorithm visualizer for maze generation and pathfinding, with step-by-step animation, deterministic seeds, solver comparison, and terminal-aware rendering.
Local-first usage meter for Claude Code and Codex sessions, with SQLite storage, token and cost history, and a private browser dashboard.
Cross-platform CLI utility in C#/.NET for one-way directory synchronization, with SHA-256 change detection, atomic file operations, and safety rails against path traversal and data loss.
