Hi, I’m Eliã, a senior frontend engineer and PhD candidate in Informatics at USI. I bring over a decade of experience delivering high-performance, scalable web applications using React, Next.js, TypeScript, and modern frontend architectures. I thrive on solving complex UX and performance challenges, collaborating with designers and backend teams to create reliable, maintainable solutions. I’m based in Lugano, open to relocation, remote work, or hybrid arrangements, and I enjoy applying systems thinking to frontend problems—prioritizing performance, reliability, and accessible user experiences. When I’m not coding, I’m mentoring juniors, researching distributed systems, and helping teams ship production-grade software.
