BrazilWhat I'm looking for
I am a Lead Software Engineer with over 12 years of experience in designing and building innovative solutions across various industries, including urban mobility, healthcare, government institutions, and banking. My expertise lies in Java and Spring Boot, where I have consistently delivered high-quality solutions that enhance performance and reduce costs.
In my recent role at VMetrix, I led the development of core modules for an international financial SaaS, focusing on architecture definition and production deployment. My achievements include successfully refactoring unstable Java modules, developing an email-sending solution, and implementing an SSO solution for seamless user integration. I pride myself on my ability to lead teams and projects that drive significant improvements in system reliability and customer satisfaction.
Throughout my career, I have embraced principles such as Clean Architecture and SOLID, which have guided my work in migrating systems from monoliths to microservices and enhancing application security. I am passionate about leveraging technology to solve complex problems and am always eager to take on new challenges that allow me to grow and contribute to my team's success.
