I’m a software developer who enjoys building thoughtful products with clean UX, solid architecture, and just enough polish to make them feel great to use.
I like working on apps that people actually use - especially projects that involve local-first data, sync, mobile UX, and subtle motion. I care a lot about when to build a feature just as much as how to build it.
- Rep — a local-first workout tracking app with sync, social features, and native charts
- Written — a privacy-focused journaling app with encryption, local-first storage, and on-device AI
- Dash — a running app MVP with native map and GPS features built in Swift
- INVT — an event platform with QR invites, ticketing, and Stripe marketplace payments
Most of my projects start small, ship early, and grow only when real usage justifies it.
- Frontend: React, Next.js, React Native, TypeScript, Tailwind, shadcn/ui
- Mobile: Expo, native modules, Swift
- Data & Sync: Supabase, PostgreSQL, WatermelonDB, Dexie
- UX & Motion: Motion, subtle animations, interaction-focused UI
- Other: Stripe, Web Push, local-first patterns
- Ship an MVP first, refine with real usage
- Favor clarity over feature count
- Keep interfaces calm and intentional
- Treat performance and UX as product features
- Build systems that are easy to evolve
