About

Hi Everyone! I'm a software engineer with over four years of solid experience in Java, mainly with Spring Boot. I have worked for several companies in the financial and logistics sector building REST and event-driven applications. Beeing a challenge driven person, I'm always seeking opportunities to improve the context I'm working in, bringing newer technologies, enabling observability among other important and out of scope value. Currently working on the digital transformation of a major credit union in Brazil, working daily with Apache Kafka, OracleDB, MongoDB, Spring Boot, and Apache Flink, developing and evolving the application to a robust solution that enables the company's projected growth. I have worked before with investments integrating with the brazilian stock market at the same company. Since the beginning of my carrer I consistently pursued projects with potential for learn and impact on the companies I worked for, so I'm always open to opportunities that can bring professional development and high value to organizations. I have strong communication skills witch helped create better solutions countless times and am always eager to help transform a project in reality! Let's connect!
