Software Engineer

Prill Tecnologia•  November 2012 - May 2019

Prill Tecnologia is a consulting company that works for some of the biggest players in sectors like Telecommunications, Insurance, and Financial. I have worked as a software developer on many challenging projects for those companies. In the telecommunications field, we built tools responsible to generate a broadcast of 10 million short messages (SMS) every day and providing customers with real-time location-based services for emergency call centers. These services were written in Java, using Apache Camel and Weblogic. We built some products for a subsidiary of a major Brazilian insurance company, including an Open API using REST, constructed over the IBM environment. We also develop services through Java JEE with WildFly and maintained COBOL services and C libraries. For the Financial field, we developed many projects as an outsourcing company for the Brazilian stock exchange, implementing all the requirements listed in the specification that came from the client. Almost all the development was made in Java, PL/SQL, and shell scripting.
