Senior🎓
Top SchoolVishal Sahu is a Senior Software Engineer with 11 years of experience building large-scale, stateful sharding and capacity-planning systems, currently at Meta where he contributes to the Global Shard Placer and ShardManager teams. He specializes in constrained optimization for global replica placement, dynamic shard migration, load balancing, failover, and disaster-readiness across multi-region deployments. Vishal has a strong systems and storage background from roles at Dell EMC and Samsung, including kernel-level data protection features and imaging/video algorithm implementations. He is experienced running major production capacity events such as new region turn-ups, decommissions, and DR buffer estimation, bringing both operational rigor and architectural insight. Based in Bellevue, WA, he pairs academic training (MS in Computer Science from Stony Brook) with hands-on expertise in distributed systems and embedded/firmware-level engineering. A detail that often surprises peers: he has shipped both high-level global optimization engines and low-level kernel features, bridging the gap between algorithmic placement and brutal production realities.
