What I'm looking for

I seek frontend roles focused on React/TypeScript where I can build scalable, testable systems, mentor teams, and improve observability and developer experience.

I am a frontend developer with six years of experience building scalable, user-focused web and cross-platform applications using React, TypeScript, React Native, Next and PWAs. I prioritize code quality through comprehensive unit testing with Jest and by implementing robust tooling for monitoring and feature toggling.

At Flash I led delivery of the first micro-frontend, built vacation and shift-management workflows, and implemented a BFF with tRPC while introducing Unleash and Sentry/Grafana for observability. At Anheuser-Busch InBev I contributed to a shared component library and delivered MVP platforms for internal stakeholders, improving reuse and time-to-market.

Earlier roles include work on e-commerce landing pages and interactive customer experiences for Grupo Boticário and full-stack/mobile responsibilities at Streammus, where I migrated a PhoneGap app to React Native and maintained backend APIs. I bring a pragmatic, collaborative approach and a track record of shipping reliable, maintainable front-end systems.
