  Senior Software Engineer

  I led the frontend team, and I was responsible for the definition of the product tech Stack from scratch (based on some pre-defined premises (Angular 2+ and Java Microservices)). I suggested for the team adopt the Gitflow methodology, with some well-defined Code Standards, and Pull request processes, always using the Feature branches concept. Together, we reached very good results, considering the quality of the product (tested, well structured, and easy to maintain for every developer), and also based on the feedback of the clients.Another important accomplishment that I consider is how the entire team has grown technically during this period.
