Principal Android Engineer for the Seller team.
Worked as a principal for four teams with about 30 engineers, coaching them, reviewing their designs, and improving the team's operation through all the engineering areas of the Seller team: backend, web, Android, and iOS.
Led and designed a Native Questionnaire for Android and iOS to substitute a web version of a questionnaire.
Improved the efficiency of the mobile team by increasing the sprint velocity, coaching the team to focus on getting things done and moving faster through tickets, increasing each team from about 20 points per sprint to around 50 points per sprint.
Created a Versioning Policy for the back-end, front-end, and mobile teams to follow when updating the questionnaire so they could ensure changes were homogeneous through the different platforms.
