Progressive Flagr
Flagr is an open-source AB Testing and Feature Flagging microservice. I was hired by Progressive to add features and improve the performance of an inner-source branch of Flagr.
Among other features, I added RBAC, new convenient API methods, and time-based constraint types. I also executed a large refactor of the codebase, resulting in ~80k less total LoC, and a 10x reduction in average response time. I mentored other developers working on Flagr and led teams of contributors in inner-source code jams.
We hope to open-source our branch of Flagr in the near future.
