Staff/Principal engineer & architect. I own backend and mobile systems end to end: Node/TypeScript, GraphQL, React Native, AWS. Remote, US time zones.

Message

I'm a Staff/Principal-level engineer, architect, and engineering manager based in Costa Rica. At Strong Strong Friends I lead engineering for "Stronger by the Day," a fitness app, and for its sister company Trainmakr, which builds white-label coaching apps for personal trainers.

I own systems end to end, from architecture and hiring to shipping and operating in production. My core stack is Node.js/TypeScript, GraphQL/Apollo, PostgreSQL, Redis, React Native/Expo, and AWS. I've built multi-tenant platform architecture, video infrastructure, role-based access control, and a mobile attribution stack spanning web checkout, Amplitude, AppsFlyer, and Stripe.

Outside my day job, I build and run automated algorithmic trading pipelines for crypto and forex, and I work hands-on with the Anthropic API. That keeps me sharp on applied AI, data-heavy systems, and reliability under real-world conditions.
