I build scalable, accessible React applications backed by 20+ years of infrastructure and systems experience.
BrazilWhat I'm looking for
At ArcTouch, I build production-grade React and TypeScript applications for organizations including HP, Cirrus Aircraft, AKQA, Starbucks, and Quizlet. I create scalable, responsive, accessible interfaces, reusable components, and maintainable frontend architecture while collaborating closely with design, product, and backend teams.
Before ArcTouch, I led A1 Tecnologia Industrial's growth from roughly 60 to more than 1,000 endpoints, modernizing infrastructure through VMware, Microsoft 365, pfSense, VLANs, monitoring, and disaster-recovery planning. I bring more than 20 years across software development, systems administration, networking, security, and open-source work, including Next.js and React component projects.
