Web3 Security Engineer with 3+ years in blockchain security and 4+ years in cybersecurity, currently securing a live EVM-compatible L1 blockchain at Shardeum under Nischal Shetty. I own security end-to-end — from protocol-level vulnerability research and smart contract auditing to cloud infrastructure hardening and validator key management. At Shardeum, I managed $1.3M in Immunefi competitive audit rounds, owned the triage-to-fix lifecycle across the Shardus-based L1, and led security for the Cosmos SDK-based Mainnet 2 pivot — architecting sentry-based validator isolation and engineering TMKMS + GCP KMS consensus key security. I also author and audit DeFi smart contracts, and define threat models for external auditors including Sherlock, Cyfrin, and CertiK.
