Engineering Manager in Brazil. After hours I still build things end to end: desktop and web apps, PWAs, a few things that run on a Raspberry Pi or an Arduino, and tools that make working with Claude Code faster.
| Project | What it is |
|---|---|
| markdown-viewer | Notes app that opens an Obsidian vault as-is, with end-to-end encrypted sync and an MCP server. Tauri + Rust + Cloudflare. |
| Legato | Piano PDF to MIDI for Synthesia. Reads the vector notation and refuses instead of guessing. |
| feedback-kit | One feedback queue for all my apps. Claude Code works on the notes and records exactly what it did. |
| ChordLab | Chord training on a MIDI controller, right in the browser. |
| DailyFlow | The day as a living plan: plan × reality, on web, Android, Wear OS and desktop. |
| Guitar Lab | Scales and chords in every CAGED shape, with practice in loop. |
| TuneDeck | A musical repertoire as a kanban board. |
| Backlog | Movies, series, games and books, with where to find each one. |
| Revisor Visual | Browser extension to review a page by clicking on it and hand Claude Code the exact fix. |
