• Project Overview: Rocketpool is a decentralized staking protocol with flexible entry requirements, compatible with Ethereum and mainstream Layer2 networks (Optimism, Arbitrum, Polygon). It simplifies staking, reduces participation barriers, and enhance security through node operation mechanisms and flexible minipools. Key features include a DAO governance to ensure transparent development, a dual-token economic model for liquidity and governance rights distribution, a delegating staking mechanism and only-ETH staking to boost user growth by 20% annually, and an out-of-the-box node operation package to lower technical barriers. • My Responsibilities: 1. Smart Contract Development and Optimization: Responsible for developing and optimizing efficient and secure core smart contracts. 2. Protocol SDK in Go: Developed 4 core modules of a SDK for high-performance interaction between the users and contracts, targeting normal staking users and node operators. 3. Node Operation CLI Tools: Provided user-friendly CLI tools and Docker container support for node operators, improving deployment efficiency by 2x. 4. Security Testing and Audits: Conducted self-security testing of the protocol，cooperated with audit companys and fixed 3 major vulnerabilities.

• Project Overview: Golom is a decentralized NFT platform with low-entry barriers, offering NFT minting, trading, order expiration, ownership, etc. It adopted Golang, Solidity, Hardhat, go-ethereum, Redis, and MySQL, which is compatible with mainstream Layer2 for efficient and low-cost transactions with 40% lower gas cost, boost artist earnings by 10% with user-defined royalty. • My Responsibilities: 1. Backend Web Service: Developed using Golang and Gin to achieve high-performance smart contract interaction and smooth user experience, as well as performance optimization 2. Smart Contract Development and Testing: Built upgradable NFT contracts based on Orderbook model, ensuring gas efficiency and conducted testing deployment via Hardhat to ensure security (including reentrancy locks, permission control, parameter verification, etc). 3. Blockchain Synchronization Service: Achieved data synchronization using go-ethereum + Redis + MySQL to store user and transaction data and ensure near real-time updates and improve data query efficiency by 5x.

• Project Overview: Maintained a core data service platform for top-level business, based on Springboot + Kubernetes + Redis + HBase. It offers low-latency, high-concurrency, real-time data analysis for data consulting and decision analysis scenarios, which processes 200TB of data daily. • My Responsibilities: Platform architecture and technical iteration, optimizing latency from 300ms to 50ms and save query and storage costs by 75%. Built CI/DI pipeline on Kubernetes microservices and produce a SOP for the team, and closely communicated with business departments to provide data support for business development.
