About Me

Senior Software Engineer with experience in Machine Learning and distributed systems, having a continuous hunger for knowledge. I have a passion of Java with experience in SpringMVC, Scala, Hadoop, Spark, Jersey, JavaRx, Spring React, Hibernate, JUnit, Gatling, PIT Mutation Testing and Cucumber. Besides, I also have experience with CI tools like Jenkins, TeamCity, SonarQube, CSpider and Nolio. In the future I want to become an expert on the JVM ecosystem. I have a born nature to do things in the right way and I don’t settle on the first version on the solution.
