At Datalastix, I’m driving the transition from a legacy monolith to distributed microservices, improving response times by 25% and accelerating feature delivery. I also optimize React.js and Angular applications, reducing Core Web Vitals by up to 40%.

I develop Python automation with Selenium, Playwright, and PyAutoGUI, integrating it into CI/CD pipelines to reduce processing time and minimize manual errors.

At Caixa Econômica Federal, I optimize customer service platforms, including Atendimento SAC and Resolve.Caixa (SISOU). My work on these systems improved transaction integration rates by up to 40% and reduced incident rates by 35%.

Earlier, at Prolink Computação, I developed a Ruby on Rails dashboard that increased new student registrations by 30%. I’ve also built automation and web solutions using Java, C++, PHP, and JavaScript.
