What I'm looking for

I'm looking to lead frontend architecture and distributed engineering teams while building scalable React products, design systems, AI-enabled interfaces, and reliable API-driven workflows.

I'm currently leading frontend architecture at FreeBalance, where I mentor three senior developers and build shared libraries across four enterprise web portals. My work has reduced frontend redundancy by 40% and improved feature time-to-market by 25%.

I've modernized legacy platforms at Briteris/Iteris, Avantica/Encora, and Partsbase by migrating AngularJS and legacy MVC applications to React, TypeScript, and component-driven architectures. These efforts improved page-load performance, bundle size, developer velocity, and maintainability.

At iDo Agency and Kronoscode, I built Shopify Admin applications, custom API integrations, Node.js services, and headless storefront experiences. I also improved checkout workflows, mobile performance, and reliability for high-traffic e-commerce stores.

Across 14 years in web engineering, I've led distributed teams, applied DDD and Clean Architecture, facilitated Scrum practices, and built AI UI prototypes using structured JSON outputs. I enjoy aligning technical strategy with business goals in English and Spanish.
