I build developer tools that integrate AI into everyday workflows.

pdf2anki -- A Python CLI that generates Anki flashcards from PDF/text/Markdown using Claude AI. Features Vision support, TUI review, caching, and an eval framework.

daily-research -- Automated daily research reports powered by Claude Code. Zero Python — just shell scripts and prompts. Runs every morning at 5 AM via macOS launchd.

claude-code-learned-skills -- Practical patterns and best practices extracted from real-world Claude Code usage.

I write about Claude Code, AI automation, and developer workflows.
