What I'm looking for

I am looking for a challenging role in a dynamic company that values innovation and offers opportunities for professional growth.

As a seasoned Java senior engineer, I have dedicated my career to developing and implementing comprehensive e-commerce solutions. With a Bachelor's degree in systems analysis from PUC-RIO, I have honed my skills in Java (versions 8 to 21) and SpringBoot, enabling me to build robust and scalable applications. My experience spans across various roles where I have successfully designed and managed microservices, optimized application performance, and ensured software quality through rigorous testing methodologies.

Throughout my professional journey, I have played a pivotal role in transitioning monolithic systems to microservices architectures, enhancing flexibility and scalability. My expertise extends to managing databases such as Postgres and DynamoDB, implementing Kafka for efficient communication, and configuring CI/CD pipelines with Jenkins to streamline deployments. I am passionate about code refactoring and maintaining legacy systems, ensuring they meet modern standards while delivering high performance.

My work has not only focused on technical excellence but also on collaborating with cross-functional teams to deliver solutions that meet business needs. I thrive in environments that challenge my skills and allow me to contribute to innovative projects, particularly in the e-commerce sector.
