What I'm looking for

I'm looking to build scalable, high-performance web applications with React, Angular, and TypeScript, contribute to design systems and engineering standards, and collaborate with international Agile teams while mentoring other developers.

I've built and maintained SaaS retail platforms at Inteliger, including Voái Performance, serving more than 20,000 daily active users, and Voái Venda Mais, responsible for over R$160 million in processed transaction volume.

At GFT Technologies, I develop high-impact web applications for an international financial-sector client using React, Angular, and TypeScript. I contribute to a reusable private UI component library, integrate RESTful APIs, and work closely with UX/UI teams to deliver responsive, user-centered interfaces.

My work centers on scalable SPAs, Design System architecture, and reliable delivery through Jest, Vitest, and Playwright testing. I've also led code reviews, onboarded and mentored developers, and taught technical bootcamps for new software engineers.

I'm fluent in English and comfortable collaborating with distributed international teams in Agile environments using Scrum and Kanban.
