About

I am a backend development specialist with 17 years of experience delivering complex software solutions for public institutions and major companies in the financial and technology sectors. I have deep expertise in Java, Spring Boot, microservices, and cloud architectures (AWS), working on both greenfield development and legacy system modernization. My work involves API integration, asynchronous messaging, performance optimization, and high-volume data processing—always with a strong focus on code quality, automated testing, and software engineering best practices. Throughout my career, I’ve contributed to critical systems at organizations such as GFT Technologies, Zup Innovation (serving Itaú Unibanco), and federal universities, participating in mainframe integrations, cloud-native implementations, and infrastructure improvements. Beyond technical expertise, I bring essential soft skills for high-performance environments: clear communication, active listening, strong collaboration, mentoring junior developers, and close alignment with product and business teams to maximize the value of our deliveries. I hold postgraduate degrees in Software Engineering, Artificial Intelligence, Mobile Development, and Computer Engineering. I believe software excellence comes not only from technical mastery, but also from empathy, adaptability, and strategic thinking. I am committed to continuous growth—combining technological innovation with a strong focus on building efficient, sustainable solutions that meet real user and business needs.
