Web3 Qa Engineer / Blockchain Node Operator
15-year tech veteran transitioning to Web3 with a strong focus on Security and Infrastructure.

Core Value:
- QA & Security: Expert in manual testing, Etherscan transaction analysis, and identifying smart contract risks (Honeypots/Slippage).
- DevOps & Nodes: Proficient in Linux server management, Nginx configuration, and running RPC nodes (Geth/Reth).
- Reliability: Steady, meticulous, and process-oriented. I bring stability to fast-paced teams.
Currently seeking QA Engineer, Technical Support, or Junior DevOps roles. Fluent in Chinese, professional working proficiency in written English.
