I'm a Senior Frontend Engineer with over 6 years of experience building and maintaining production-grade web applications.
I focus on turning complex requirements into clear, scalable interfaces, with strong attention to performance, maintainability, and long-term code health. I care not only about how systems look on day one, but how easily they can be understood, modified, and extended over time.
I've worked in remote-first teams, collaborating closely with product managers, designers, and engineers. I value clear communication, documented decisions, and pragmatic trade-offs over both over-engineering and under-engineering. Beyond implementation, I contribute to architecture discussions, help define meaningful testing strategies, and support teams through refactors and incremental improvements.
I believe good frontend work is invisible when done right and I aim to build systems that teams can trust and evolve with confidence.

  I worked for more than 2 years on the same team as Guilherme. I had an incredible work experience with him; he was very helpful and available, engaged in solving the proposed problems and always questioning, trying to find the real impact of the activities he carried out, always very concerned with quality and deadlines. I would be very happy working with him again on the team because I know he will deliver great work.
