Summary

Founding engineer focused on distributed data systems and a fresh API for streaming: Shikhar co-founded S2 (Stream Store) to make streams a first-class, serverless cloud storage primitive. His work spans system architecture, Rust SDKs/CLI, and production-focused concerns (latency tiers, storage classes, and multi‑tenant serverless design). s2+2
Practiced at making distributed systems reliable: he emphasizes deterministic simulation testing (DST) for reproducing concurrency and failure modes in a Tokio/Rust codebase, and has published technical posts on applying DST to S2's development and CI practices. s2+1
Open-source contributor and researcher with networking tooling roots: as an undergraduate he co-authored NCClient (a Python NETCONF client library) and has long-standing OSS contributions (including work acknowledged in sshj and public GitHub repositories). This background complements his systems-and-infrastructure work at established companies and startups. springer+2
Experienced across large engineering organizations and startups: Bhushan has held engineering roles at companies such as Etsy (search/retrieval infrastructure), Bloomberg, Confluent, Facebook, and later shifted to founding and operating product-focused infrastructure startups (S2 / Stream Store and Bandar Systems). berlinbuzzwords+2

Deterministic simulation testing for async Rust

April 1, 2025

Technical write-up about using deterministic simulation testing (DST) techniques for a Rust/Tokio codebase to find hard-to-reproduce distributed-system bugs; discusses tooling and approaches (Turmoil, MadSim, etc.) used while building S2.
