// About me

From Physical Therapy to software engineering for healthcare

I'm a Full Stack Developer working with React, Next.js, Angular, Node.js, TypeScript and Go. I build intuitive, responsive interfaces and robust, scalable APIs, always keeping an eye on performance, process automation and cost reduction.

Today I work at Mobilemed Soluções Médicas, on the cloud PACS and teleradiology platform used by clinics and hospitals. Before that, I led web development at Biointegral Saúde Clinic, where I built an e-commerce platform from scratch, financial and patient-flow systems, and tools that cut operating costs by 15%.

I come from Physical Therapy, which gave me empathy for the people who use the product, team leadership and attention to detail. I have international experience in France and the United States and speak English (C1) and French (B2), which makes working with global teams easier.
