What I'm looking for

I'm looking to build scalable, business-critical products where I can combine full-stack engineering, AI-assisted development, rigorous quality practices, and technical leadership.

I've built and maintained full-stack features for Airtm, a global digital financial platform, using React, Node.js, JavaScript, TypeScript, GraphQL, PostgreSQL, Kafka, Redis, and Kubernetes.

I use Claude Sonnet and Claude Opus for planning, code generation, testing, review, refactoring, and debugging, reducing select feature delivery from roughly two days to a few hours while improving release stability through rigorous manual QA.

I've also delivered web platforms for Keller Williams, PayPal, CESEM, and technology organizations in Peru. As CTO at Emesh Latinoamerica and Director at Equipo Atix Plus, I grew and led teams, shaped architecture, mentored developers, and delivered software for private and government clients.
