Tollitech
Thoughtful, local-first software built for calm focus.
I build offline-first, cross-platform apps that respect your data, stay out of your way, and work wherever you do—from tabletop RPG companions to ADHD-friendly personal planning.

Dice Caster
Polyhedral Dice Roller

Citrine
ADHD-Friendly Notes & Task Management
A calm, adaptable personal system for capturing thoughts, organizing notes, and managing tasks without rigid structure, streak shame, or cloud lock-in.
Core Philosophy
Every project shares the same foundation.
Local-First & Private
Your characters, notes, and tasks live locally on your own devices. No forced cloud accounts, no subscriptions, and no external dependency just to use your own data.
Calm Complexity
Powerful systems shouldn't feel visually or cognitively overwhelming. Progressive disclosure keeps day-to-day workflows clear while leaving depth within reach.
Portable & Durable
Software should adapt as your needs evolve. Open formats, modular rules, and customizable workflows prevent lock-in and respect your time.
