Senior Solidity & Rust Engineer
Web3 & Layer 1/Layer 2 On-Chain Protocol Full-Stack Architecture
Public Chains & Consensus Mechanisms: Deep expertise in Layer 1 public chain architecture design; hands-on engineering experience in POS/POC consensus mechanisms, parallel on-chain transaction processing, and high-TPS (5000+ TPS) performance tuning.
Smart Contracts & Security: Proficient in Solidity and Rust; deep understanding of EVM execution mechanisms, Gas optimization, and security audit standards (e.g., reentrancy attack prevention); expert in standard protocols including ERC-20, ERC-721, ERC-1155, and Multi-sig contracts.
RWA (Real-World Asset Tokenization) & DePIN: Architected on-chain mapping for RWA assets, including reserve asset verification, automated on-chain yield distribution, Oracle integration, and decentralized storage (IPFS / Filecoin / BNB Greenfield); experienced in optimizing distributed routing algorithms and Proof of Storage (PoSt/PoRep).
Ecosystem Components & Cross-Chain Protocols: Full-stack R&D delivery experience (from 0 to 1) across non-custodial wallets, cross-chain bridges (featuring multi-sig verification and secure routing), DEX/Swap platforms, and DeFi staking protocols.
AI Agent + Web3 Native Integration
Expert in designing state-machine AI agents and multi-agent collaborative systems based on LangChain and LangGraph.
Production-grade delivery experience integrating AI Agents with Web3 non-custodial wallets (Web3 Auth), smart contract triggers, and on-chain data parsing (The Graph / RPC).
Distributed Infrastructure & Low-Level Security
20 years of expertise in high-concurrency distributed architectural foundations; proficient in Node.js, Python, Java, and Go.
Skilled in cloud-native Docker/Kubernetes cluster deployments, Cloudflare edge computing, and globally available high-availability RPC node infrastructure.
Web3 Team Management & Tokenomics
8+ years of CTO/Chief Architect leadership experience, managing cross-functional/multinational blockchain engineering teams of 30–50 people.
Deeply involved in Tokenomics design and DAO governance implementation.
