Summary
👤
Senior🎓
Top SchoolGuilherme Santos is a Lead Software Engineer based in Santa Catarina, Brazil, with over a decade of hands-on experience building and scaling web applications, primarily focused on front-end engineering and design systems. He has progressed from Java EE and full-stack roles to leading front-end efforts at Nubank and other major fintech and enterprise clients, routinely shipping TypeScript/React solutions and reusable component libraries. Guilherme blends product-minded engineering with developer experience improvements—he’s led platform squads, defined front-end standards, and built design systems used across organizations. He has startup founder experience (igotten), giving him practical empathy for MVP delivery and cross-functional collaboration. Comfortable in both fast-moving fintech environments and regulated enterprise settings, he pairs technical depth with a user-centered interaction design background. An underrated strength is his repeated pattern of improving team velocity and reliability through tooling, testing, and developer guidance rather than just individual feature delivery.
