What I'm looking for

I seek a collaborative environment that values innovation and offers opportunities for growth.

I'm a dedicated backend developer with a bachelor's degree in Software Engineering and over four years of experience in crafting innovative software solutions. My expertise lies in Java, particularly with frameworks like Spring and Quarkus, where I focus on building robust distributed architectures and ensuring seamless systems integration. I thrive in agile environments, utilizing methodologies such as Scrum and Kanban to deliver high-quality software that meets user needs.

Throughout my career, I've successfully implemented REST APIs and microservices that enhance operational efficiency and reliability. For instance, at Leega, I played a pivotal role in developing services for Santander Bank, which improved data processing times by 50%. My commitment to best practices, including SOLID principles and Clean Architecture, has consistently resulted in reduced maintenance times and lower error rates in production. I am passionate about leveraging technology to solve complex problems and drive business success.
