Technical direction without leaving delivery behind.

I work across architecture, planning, implementation, and delivery. The job is to help teams make clear decisions and ship software that holds up in production.

About me

Engineering lead with 15+ years building web products and backend systems across media, finance, healthcare, IoT, and utilities. I lead teams, technical direction, and delivery while staying hands-on with architecture and implementation. I am also part of DOMOS, TRIBU Tech Latam's network for technology leaders across Latin America.

Experience

Most recently, I have led frontend architecture and delivery for media platforms used by Pluto TV and Warner Bros. Discovery. The work includes microfrontends, identity and platform integrations, CI/CD, supporting Node.js and Go services, and a media-submission portal that caught file problems before upload. Earlier work includes products for Indeed, Greenway Health, Aclara, Deloitte, and credit bureaus across Latin America.

Skills

Team leadership, delivery planning, and software architecture are the core of my work. My current stack is mostly TypeScript, React, Node.js, Go, microfrontends, CI/CD, AWS, Docker, SQL, and AI-assisted development. I also have years of experience with Angular and C#.

Writing

I write stuff about software engineering, AI, architecture, leadership, and what happens when real teams have to ship real software. Read the blog.
