Web3 Talent

@jhcc

Experienced in production-grade blockchain infrastructure and transaction-level performance tuning in distributed environments.

Improved Hyperledger Besu throughput by 27x (25 TPS → 678 TPS) through concurrency optimization and transaction isolation redesign. Designed and integrated ZK proof systems reducing decryption time from 35s to <1s.
