Lights out. Take Marksage for a lap →
A Markdown editor that runs its own ML models inside your browser.
By day I keep real deliveries moving on a logistics platform. By night I build side projects that train their own models, and I measure them before they get anywhere near the track. Cursor, Codex and Claude sit on the radio as race engineers; the strategy calls stay with the driver.
Side projects, 2026 season

| P3 | Loreforge AI-first tabletop RPG platform. One grid engine runs on server and browser, so nobody peeks through the fog of war. |
