What I'm looking for

I'm targeting Senior Frontend Engineer, frontend-focused Software Engineer, React Tech Lead, and Frontend Architect roles where I can build scalable React architecture, improve performance and delivery speed, and mentor engineers.

At Webmotors, I architected a micro-frontend ecosystem with Webpack Module Federation that enabled four-plus product teams to deploy independently and reduced feature release cycles by 40%.

I've optimized CI/CD with GitHub Actions and Jenkins, cutting average build times by 70%. I also improved high-traffic CRM performance through virtualized lists, lazy loading, and code-splitting, increasing Lighthouse performance scores by 25%.

Previously at Centro Universitário São Lucas, I built a responsive student portal for 5,000+ active users and improved academic resource accessibility by 30%. I created 15+ documented reusable UI components, reducing feature development time by about 30% across multiple projects.

I focus on React, TypeScript, frontend performance, testing, and scalable architecture. I've mentored mid-level developers and built quality practices with Jest and React Testing Library that achieved over 90% coverage for core features.
