What I'm looking for

I’m looking to grow in a product-focused team where I can modernize legacy frontends into modular architectures, build high-performance React/Next.js experiences, and deliver production-ready SaaS features with Clean Code, CI/CD, and strong collaboration.

I’m a Senior Frontend Engineer with 15+ years of experience building and maintaining high-traffic SaaS platforms. I’m expert in React (6+ years) and Angular, specializing in TypeScript and performance optimization, with a strong focus on Clean Code.

I’ve led modernizations of critical legacy frontend modules into modular architectures, including migration work that improved UI consistency for thousands of daily users. I’ve collaborated across distributed global teams (US/LATAM), delivering production-ready features with high engineering standards and close Product and Design alignment.

Across my roles, I’ve built and scaled multi-tenant features, optimized responsiveness through advanced state management and lazy loading, and reduced technical debt through refactoring. Today I’m expanding my expertise in Next.js (App Router) and modern state management, including Zustand and TanStack Query.
