Rockstar🎓
Top SchoolHari Sunder is a Principal Engineer based in the San Francisco Bay Area with a deep focus on distributed SQL databases and cloud-native reliability. He has built core distributed systems at Microsoft for Azure SQL and Synapse—designing metadata, lock, and transaction managers—and now drives high-performance PostgreSQL-compatible features at YugabyteDB, including xCluster replication, pg_cron and multi-API support. Known for turning prototypes into production-grade architectures, he helped deliver 99.995% availability guarantees for millions of Azure databases. With a BTech from NIT Tiruchirappalli and a hands-on engineering career that spans high-throughput replication to online upgrades and rollback tooling, he blends low-level systems rigor with product-minded engineering. An understated strength is his track record of shipping the invisible plumbing that keeps large-scale cloud databases both fast and resilient.
