I've built offline-first mobile workspaces, e-commerce systems, financial dashboards, and real-time collaboration tools using React, React Native, NestJS, and PostgreSQL.

For AgentAide, I engineered a 100% offline-first workspace for real estate agents, using Expo SQLite for zero-latency local queries and a Supabase bridge to sync OCR-extracted boarding-pass data to live web links.

I've also developed ACID-compliant checkout flows, serverless Redis caching, JWT authentication, WebSocket collaboration, and scalable database schemas for production-oriented applications.

My earlier web development work modernized local business and municipal operations, while more than four years translating technical and business materials has strengthened how I communicate across distributed, bilingual teams.
