Reduced compile times by 7 minutes by the creation of a service side Swift service with a companion Ruby service that tracked build times locally and on CI, which helped us track major bottlenecks that guided us towards improving our project organization; resulting in more developers embracing TDD due to lesser turnaround times which lead to an increase in the confidence of shipping new features. Reduced the number of flaky tests on the iOS code base by implementing a Swift server side service that scrapes and parses CI data from Buddybuild, to generate metrics and dashboards that helped us track and fix flaky tests and confirm improvements via metrics; which lead to minimizing friction when adding new features and reducing the integration time by 50% as a result of reducing the need to re-run the CI jobs to verify flakyness. Improved initial playback time and playqueue load times by 15 seconds by extracting and refactoring Offline Sync into it's own framework and removing unnecessary complexity; leading to an increase in total listening time of our users by 10%. Wrote multiple tools that hookup to Prometheus in order to properly analyze and maintain app health as well as to better understand how all the systems interact with each other.
Architected and defined the infrastructure for modules/framework extractions into micro features. Integrated the new in-house media player into the iOS application; leading to less crashes, faster remote media loading and caching as well less fragmentation of the code via guiding all the media playback through the same engine (audio & video).
