About Me

I work on Ethereum core protocol engineering across both the Consensus and Execution layers. I will be joining the Ethereum Foundation’s Specification & Testing team,focusing on consensus-layer

Work History

Ethereum Foundation — STEEL (Specification & Testing), Consensus Layer

Incoming — June2026

Ethereum Foundation — Ethereum Protocol Fellow

Implemented FOCIL (EIP-7805) fork-choice logic in the Nimbus consensus client.
Contributed to Pureth (EIP-7919): SSZ-native execution data structures replacing legacy RLP/MPT models.
Implemented EIP-7745 (Trustless Log Index)) in Nimbus EL, enabling provably complete eth_getLogs responses without reliance on external indexers.
Contributed to execution-spec-tests and Hive-based cross-client differential testing.

Zero Knowledge Engineer — OpenPassport

Designed and integrated a zk-proof pipeline for Aadhaar-based identity verification.
Optimized proof verification latency and improved throughput.
Built unit and integration testing infrastructure for cryptographic correctness.

Research Interests

Distributed Consensus: Fork-choice rules, proposer/builder separation, censorship resistance.
Zero-Knowledge Proofs: STARKs, zkVM design, AIR, FRI, polynomial commitments.
Execution Layer Architecture: SSZ-native models, statelessness, provable RPC.
Compiler Design: Intermediate representations, optimization pipelines, SIMD-aware compilation.
High-Performance Computing: Parallel proving systems, memory-aware and cache-efficient design.
Cryptographic Protocols: Secure communication schemes and blockchain primitives.

Other Interests

Low-level architecture & instruction set design
Parallel computing and SIMD optimization
Football, cricket, music, and video games
