- 💬 Ask me about: React Native performance, strict TypeScript, Supabase RLS, publishing apps to the stores
- 🛡️ Zero
any: strict TypeScript everywhere. Fewer runtime errors, better DX. - 🔒 Security by default: Supabase Row Level Security on every table, no exceptions.
- 📶 Offline-first: SQLite locally, synced to Supabase when online. Built for unreliable networks.
Source code is private. Each project has a public showcase with screenshots and architecture.
