What I'm looking for

I’m looking for a remote-friendly role where I can own React/TypeScript UI end-to-end, build offline-first high-performance products, and collaborate asynchronously with AI-assisted workflows—prioritizing accessibility and measurable quality.

I’m a senior front end engineer with 10 years of experience building React products for web and mobile. I focus on shipping reliable UI with strong component architecture, performance optimization, and accessibility.

For 4+ years, I owned features end-to-end for a US-based company (TouchSource, Colorado) fully remote from Brazil. I architected and maintained a React platform used by internal teams to configure and deploy interactive display systems, and I extended it to a mobile-first experience for field teams.

I’m proactive about quality and iteration: I’ve optimized Web Vitals on high-traffic pages, ran A/B tests on conversion surfaces, and rebuilt front ends to improve load times. I also build async-first, written-communication habits that keep delivery smooth across time zones without on-site visits.

My approach blends modern engineering with practical AI assistance. I’ve shipped daily inside an AI-integrated development pipeline (Claude Code, GitHub Copilot) and built an offline-first Progressive Web App (“How to 2XKO”) with installable, SEO-optimized content and serverless identity/auth support.
