• Developed applications like lockless migrations that deal with petabytes of data while considering GC

impact, throughput, I/O and memory usage. We migrated 30m users across HBase clusters using this application.

• Developed consistency management solutions for data stored on Yahoo! Mail’s Primary and Backup

metadata clusters

• Worked on the design and development of multiple cross team project components in Yahoo! Mail like GDPR, IMAP-IN backend support and application features

• Led the load balancing component for metadata clusters by automating user mailbox migrations

Worked on the legacy and next- gen large scale systems that store and cache Yahoo! Mail metadata

and search data. The metadata system serves about 500B requests per day across 50 clusters.

Developed a solution for the lease server coordination system to reduce the user facing errors during software pushes. I received the Yahoo! Individual Superstar award in the year of 2014 for this project and other Yahoo! Mail contributions during the year.
