About
Senior full-stack engineer and technical leader with production experience across enterprise, startups, and high-growth products. Former CTO. I've built and scaled mobile applications, web platforms, and cloud infrastructure from scratch to production.
Strong track record spanning PricewaterhouseCoopers, property-tech startups, SaaS event management platforms, and early-stage products taken from zero to market. Currently building AI-augmented engineering infrastructure — orchestrating 20+ concurrent AI agent sessions and managing 40+ production services. I own the full stack — from React Native mobile apps to Django and Node.js backends, from AWS infrastructure to CI/CD pipelines and product strategy.
Based in Mexico (US Central timezone). Open to senior or staff engineering and product roles where I can own architecture decisions, ship reliably, and work with teams building meaningful products. Remote.
