I am an Analyst/JAVA Developer with experience in retail, wholesale, distribution and core banking solutions.My last job was at Matera, one of the leaders in core banking software solutions in Brazil.I was able to contribute to the Matera Instant Payments (PIX) project, and Digital Twin (DTW) transaction ledger system, and worked with modern technologies such as Apache Kafka, microservices, Spring Boot.I sometimes added improvements: - In troubleshooting - I created a multi-database service using Spring Boot with the aim of identifying failures in integrations in different microservices, with this I was able to proactively locate accounts that needed adjustments, and as a result the client was able to drastically reduce ticket openings. - In addition to building several projects locally to carry out payment tests and add knowledge to the team about integration and flows of the company's solutions. - Creation of solution documentation.
