About
I'm a Full-Stack Engineer from Mexico with 4+ years designing and building event-driven platforms, REST APIs, and AI integrations. I specialize in NestJS, TypeScript, and Google Cloud — and I care deeply about clean architecture, observability, and shipping things that actually work.
Currently at Grupo Rotoplas, building the event-driven platform that syncs HubSpot CRM with logistics systems — transactional outbox, HMAC-secured APIs, full OpenTelemetry observability, and AI-assisted engineering workflows with Claude Code. On the side, contributing to a year-long project at Google.
