Summary
Java Software Developer focused on developing, implementing, and
migrating systems in complex environments. I have solid expertise in
Java, systems integration, and relational databases, as well as code
optimization skills for handling large volumes of data.
Throughout my career, I have collaborated on highly relevant
projects, applying agile methodologies and software engineering
practices to deliver efficient and scalable solutions. In addition, I
have experience with technologies such as C++, SQL, Object Script,
Ensemble, InterSystems IRIS, and Cache, with an emphasis on
systems integration and strategic planning.
I seek opportunities that allow me to apply my technical knowledge
and contribute to the development of innovative solutions, while
continuing to improve my skills in programming languages and
emerging technologies.
A graduate of the Pontifical Catholic University of São Paulo, I am
committed to constantly evolving my skills and facing new challenges
in cutting-edge software development projects.
