  Full-Stack Developer

  As part of the product team, I worked on proposing technological solutions focused on the users of Lett's platforms, always collaborating with the rest of the squad (Product Managers, Product Designers, Developers). As a key product deliverable, I carried out the architectural migration of the Web platforms, transitioning from a monolithic architecture to a service-oriented architecture. I also performed refactoring and removal of legacy code during this process. During the migration, it was crucial to exercise caution in order to carry out a progressive rollout without affecting the entire user base. This is where I gained experience with feature flagging tools. Currently, I am working in the back-office team where I was able to propose solutions to enhance the entire architecture of web application monitoring (logs, APM, etc.), and gain more experience with Site Reliability Engineering (SRE). In addition, I continue to assist the product teams in developing new features.
