I have been working with system analysis and development since 2002, which most of the time was with Java environment and Linux platform. I have experience with agile development, team leadership, software architecture, web development in frontend and backend, and nowadays I am working with mobile development with ReactJS for web development and React Native for mobile. In my backend developer experience, I have experience with java (hibernate, spring, JSF, spring boot, spring function), python (django, celery, rabbitMQ and SQLAlchemy), node js (express andadonis) and databases like oracle, mysql, postgres, sql server and sqlite.
