At OKX, I led cross-chain wallet, smart account, and DEX infrastructure initiatives across Solana and EVM. I delivered the CeDeFi Trading Wallet and built core components of OKX’s EIP-7702 wallet and Wallet Core infrastructure.

I also led the integration of 30+ multi-chain liquidity protocols, adding 600+ pools and over US$700M in accessible liquidity to the OKX DEX aggregator. I developed an AI-assisted engineering workflow spanning protocol analysis, implementation, review, testing, and production rollout.

At Binance, I architected mining services across multiple Proof-of-Work networks, increasing ETH mining profit by 4.1% and reducing uncle and orphan rates. Earlier, at Bitmain, I built performance-critical blockchain systems for mining operations, after developing embedded and IoT platform components at Realtek Semiconductor Corp.
