My first task was to work as a senior backend developer fixing bugs and adding new features to a Python project called "Portal", which is a healthcare related dashboard. After a few months I was promoted to lead the engineers working on the "Portal" project, which involved creating Jira tickets, work with team leads of other projects and work close with people of other teams such as the Marketing and Product team. The portal team was also in charge of maintaining several REST APIs used by other 1health services and apps.
