Message

At Globant, I design frontend architecture for Disney applications, including content management and subscription experiences for Disney+ and Hulu, as well as web platforms for Marvel and National Geographic. I also contribute to a large internal UI component library and design system used across Disney engineering teams.

I lead engineers across projects and take part in technical demos, candidate interviews, mentoring, and code review. I build and ship features with React, Next.js, Angular, Vue 3, and TypeScript, and work across backend services and cloud delivery.

Earlier at Globant, I led the UI maintenance team supporting shared web tools during a platform migration. I also developed National Geographic’s custom video player and main website with React, Next.js, and server-side rendering.

I use Claude Code and custom subagents in my daily frontend workflow, and I’m developing an eval-first streaming content discovery assistant using retrieval-augmented generation and AI agents. My earlier work includes building web applications and services, including a company CRM from scratch at Enmedio S.A.S.
