I am a member of the programming systems team at Uber. I have designed novel static analyses, tools and workflows to improve developer productivity. Examples include (a) automatically creating diffs to delete code related to stale feature flags, (b) generating tasks reporting concurrency/performance issues in Java services, etc.I designed and implemented a code refactoring tool, named Piranha, for deleting code related to stale feature flags. Piranha has been used to delete code in Objective-C, Java, and Swift programs, and has been deployed as part of a continuous pipeline for deleting stale flags in rider, eats and driver apps at Uber. Piranha is available as open source at <a href="https://github.com/uber/piranha.A">https://github.com/uber/piranha.A</a> study of Piranha's deployment from Dec 2017 to May 2019 at Uber shows (a) generated code cleanup diffs for 1381 flags (17% of total flags), (b) 65% of the auto-generated diffs landed without any changes, (c) over 85% of the generated diffs compile and pass tests successfully, (d) developers process more than 88% of the generated diffs, and (e) Piranha diffs have been used by more than 200 developers across Uber. A report detailing our experiences with Piranha will appear in ICSE 2020 (Software Engineering in Practice track)
