Responsible for three core components of decentralized trading infrastructure: the chain node, Oracle, and Keeper. Focused on Go-Ethereum extensions and native DEX development across consensus execution, matching, account settlement, liquidation, and on-chain/off-chain state synchronization.

1) Chain Node and Dual-Engine Coordination: Extended Go-Ethereum to coordinate Aeolus consensus with EVM and DEX execution engines. Developed block execution scheduling, cross-engine message processing, state synchronization, and failure recovery, addressing execution dependencies and state consistency across engines.

2) Native DEX Engine: Developed trading functionality for spot, perpetual futures, and TradFi markets, including order book matching, order lifecycle management, positions, cross and isolated margin, funding, and PnL settlement. Supported limit, market, PostOnly, IOC/FOK, and take-profit/stop-loss orders. Used fixed-point arithmetic and deterministic state transitions to keep execution consistent across nodes. Peak benchmark throughput reached 200,000 TPS.

3) Accounts and Liquidation Risk Controls: Developed unified accounts, subaccounts, and agent authorization, connecting EVM deposits and withdrawals with the DEX ledger. Implemented margin checks, tiered leverage, order book liquidation, liquidity vault backstops, and auto-deleveraging (ADL), handling settlement for partial fills, position reversals, and liquidation takeovers.

4) Persistence and Recovery: Developed DEX snapshots, block persistence, event output, and historical replay to recover state after node restarts, synchronization catch-up, and interrupted execution. Investigated and resolved issues involving transaction atomicity, signature verification, nonce-based replay protection, financial precision, and cross-component consistency.

5) Oracle: Built multi-source market data collection, price aggregation, and signed on-chain publishing. Integrated spot and perpetual feeds from five exchanges alongside TradFi sources for equities, commodities, and indices. Used weighted medians, MAD outlier filtering, and single-source protection, with internal price discovery during market closures to support 24/7 pricing. Published prices using EIP-712 signatures.

6) Keeper: Built an off-chain state mirror from node snapshots and incremental Kafka events, serving account, order, position, and historical queries. Developed liquidation candidate detection and signed action submission for on-chain revalidation, together with historical projections, checkpoint recovery, and same-height state drift checks.

1) Core Backend Developer for PumpBTC: Responsible for core backend development of PumpBTC point system, API services, and dashboard components using Rust, PostgreSQL, and Redis. Supported real-time point calculation across 23 blockchain networks, serving over 300,000 users with a project TVL exceeding $500 million.

2) Security Component Developer for Bridge Cross-chain Platform: Independently built a security monitoring platform for the Meson cross-chain bridge using Go, PostgreSQL, and Redis. Features include real-time monitoring of multi-pool TVL, token prices, whale wallet activities, user withdrawals, risk controls, and integrated alerting via Telegram bot and Lark. Delivered a stable system with zero production bugs.

3) Smart Contract Developer for PumpHYPE: Developed a suite of PoS staking smart contracts using Solidity, OpenZeppelin, and the Hyperliquid protocol. Enabled users to stake HYPE on HyperEVM and participate in PoS staking on HyperCore to earn rebase rewards.

4) ATTPS Cross-chain Protocol SDK Developer: Independently developed a Rust SDK supporting both ATTPS EVM and Solana contracts. The SDK enables cross-chain interaction and on-chain data parsing between EVM and Solana ecosystems.

5) Backend Developer for BTCfi Project: Solely responsible for backend development using Rust. Implemented real-time TVL and APY calculations for contract pools, and integrated an off-chain Oracle for real-time token price updates.

6) Moss AI – Crypto Tweet Analysis Workflow: Designed and developed an AI-powered workflow using LLM APIs to analyze crypto-related tweets. Leveraged vector databases to support modules such as token price MCP and sentiment MCP, and automatically generated personalized user reports.

7) Blockchain Research and Documentation Specialist: Conducted deep technical research on dozens of blockchain projects including LayerZero, DODO, and Lido. Authored over 100 comprehensive development documents and successfully applied insights to real-world project implementations, showcasing strong analytical and documentation skills.

8) Hackathon Team Lead and Full-Cycle Builder: Acted as team captain in multiple hackathons, leading 0-to-1 development of projects such as optimal aggregation swap, token-equity hybrid platforms, aggregated DeFi pools, X402 payment solutions, and decentralized quantitative strategy platforms.

1) Core Developer for Bluebit Exchange: Responsible for developing a cross-chain BTC staking and reward project based on EVM, LayerZero, and Go-Ethereum. The project allows users to stake BTC and earn points as rewards, successfully deployed across multiple blockchain networks and DeFi pools. Independently developed a cross-chain data monitoring platform based on Go-Ethereum to ensure the security of cross-chain interactions.

2) Technical Manager for NFT Marketplace: Independently completed the development of an NFT marketplace, with the frontend built using Next.js, the backend using Go-Ethereum and MongoDB, and smart contracts using Solidity and Hardhat. The platform supports features like minting, buying, selling, lazy minting, and auctions for any NFT. It is currently live on Ethereum, BSC, and Polygon networks.

3) Leader in Multiple Hackathon Award-Winning Projects: Led teams to participate in several hackathons, developing a lottery GameFi project using Chainlink off-chain randomness, which won an outstanding project award and a reward of 500 USDC.

4) Passionate About Open Source: Developed and open-sourced multiple beginner-friendly blockchain DApp projects and actively organized documentation. Proficient in technologies like Solidity, Remix, Hardhat, OpenZeppelin, Ethers.js, Go, JavaScript, Go-Ethereum, Move, Rust, and LayerZero cross-chain solutions, demonstrating strong coding and problem-solving abilities.

1)Served as the Head of the Nginx Middle-End Architecture Team, responsible for Nginx development and troubleshooting complex issues.

2)Conducted in-depth research into the Linux operating systems internals and TCP network congestion algorithms, enhancing the bandwidth acceleration feature of CDN products (resulting in over 50% increase in single-server bandwidth).

3)Built the framework for large and medium-sized CDN products from scratch using Nginx+Lua mechanisms, achieving business architecture decoupling and middleware unification.

4)Built a live streaming service for a CDN product from the ground up, supporting both RTMP and FLV live streaming.
