Summary
🤩
Rockstar🎓
Top SchoolFarhan Khan is a Senior Software Engineer with 11 years’ experience building resilient, distributed systems and databases from the storage layer up. He currently contributes to SurrealDB’s core storage backend, having implemented experimental backends, configurable limits, and key upgrades that show deep familiarity with low-level data management. Previously at Codenotary he extended immudb with document-store features and efficient retention/deletion tied to Merkle proofs, demonstrating expertise in tamper-evident, auditable storage. His background spans large-scale back-end systems at VMware, Cisco and GreedyGame where he designed multi-cluster operators, gossip-based mesh protocols, CRDT-backed in-memory stores, and an RTB platform serving hundreds of millions of daily requests. Based in India, he combines strong practical engineering—especially in Go and storage engines—with a track record of improving test reliability and operational tooling. Colleagues would note his knack for tackling subtle consistency and versioning problems that live at the intersection of storage, networking and cryptographic verification.
