Stack.

What I reach for on every project.

Supabase & PostgreSQL

Auth, PostgREST, Realtime, Storage, Edge Functions and Vault, with Row-Level Security as the authorization boundary. SECURITY DEFINER functions, triggers, migrations, idempotency keys and audit logging for money-critical backends.

React & React Native

React 18/19, Next.js 14, Vite, Tailwind and shadcn/ui on the web. React Native bare CLI on the New Architecture, Expo, Reanimated, Zustand, NativeWind and Play Store publishing on mobile.

TypeScript & Node.js

TypeScript end to end: React front-ends, Node/Express and Deno edge functions, Zod-validated forms and REST APIs. Plus SQL and PL/pgSQL for the parts that belong in the database.

AI integrations

GPT-4o, vision, Realtime voice, TTS and transcription through OpenAI and OpenRouter. Tool calling, output validation, usage metering and cost control so AI features stay affordable in production.
