Projects
Built in the open.
Developer Tools
macSubtitleOCR-gui
A SwiftUI macOS app that turns PGS and VobSub bitmap subtitle tracks into SubRip text using Apple's Vision framework. Drop an MKV, pick the tracks you want, and get clean named .srt files next to your source. Signed and notarized.
Design Tools
Brand Color System
Drop in your brand hexes and get perceptually uniform shade families ready for production. Built on OKLCH so every color at the same shade step looks equally bright. Exports to CSS custom properties, Tailwind v4, W3C Design Tokens, and Adobe Swatch Exchange (ASE) color files.
Writing Tools
ProseDown
A free, MIT-licensed Python tool for writing books in Markdown and compiling them to valid EPUB 3.3. Two required frontmatter fields, CommonMark syntax, deterministic builds, and best-effort EPUB-to-Markdown deconstruction.
