Worked on Box Notes, real time collaborating and concurrent editing tool.

* Owned Box Notes distributed architecture, responsible for scaling, high availability, and disaster recovery aspects.

* Led multiple new features, all designed from scratch, with multiple developers working on each: 1) performance tweaks which resulted in infrastructure cost savings, 2) notifications which led to higher retention rates, 3) data removal service integration (compliance-related), 4) encryption/storage, and 5) led multiple high-level migrations (databases, data centers, openstack to

microservices) with zero service time interruptions.
