I graduated from the Indian Institute of Information Technology, Allahabad, and have spent most of my career working deep in the internals of large-scale data infrastructure.</p> <p>I joined Amazon in 2012, where I spent nearly ten years working on database systems at scale — tackling problems in replication, consistency, and storage. That work led to a patent, <a href="https://patents.google.com/patent/US11853321"><strong>Data Replication Without In-Place Tombstones</strong></a> (US 11853321), for a novel approach to database replication that eliminates the cost of in-place tombstone records.</p>
