About me

I’m a software engineer in São Paulo, with a full-stack background spanning infrastructure, backend, frontend, and everything in between. I’ve worked at Pagar.me and Nubank, handling high-scale, critical financial systems used by millions of people. Over the years, I’ve faced challenges in performance, reliability, modernizing legacy components, and reducing complexity - always focused on delivering faster, more stable, and easier-to-maintain solutions. And I’m also used to supporting colleagues, writing technical documentation, and actively participating in architecture discussions to help teams make clearer, more sustainable decisions.

My journey includes experiences across industries like payments, digital media, retail, and social impact. I started as a full-stack developer and have worked across backend, frontend, mobile, and infrastructure, which gave me a solid foundation to navigate different contexts and teams. I’m familiar with large-scale environments, deploying pipelines, monitoring, and all the little (but critical) details that keep a system running.

I care about clean code — but mostly about code that can be maintained over time. I believe technology is a means, not an end. And that we’re always in motion — learning, adapting, and building together.

Outside of work, I’m a father, a football enthusiast, and a hobbyist cook — always looking for the next great dish, game, or learning opportunity.
