I’m Zhang Yihang, a computer science professional with a strong focus on Artificial Intelligence and a Master’s specialization in Blockchain at Nanyang Technological University. I enjoy building real-world software systems end-to-end—turning ideas into working products—and I’m especially interested in how decentralized technologies can support reliable settlement and financial workflows. I’ve built blockchain-based settlement smart contracts using Solidity and modern tooling like Foundry and OpenZeppelin, including modules for trade netting, settlement execution, and liquidity buffering. Alongside my blockchain work, I also have full-stack development experience and solid software engineering foundations from my degree coursework, plus strong communication skills in English, with Chinese as my native language.

Work Experience

Blockchain Smart Contract Engineer (Hackathon / Project)
August 1, 2026 - Present
Built core Solidity smart contracts for a blockchain-based trade netting and settlement system, including Netting, Settlement, and Liquidity Buffer modules. Designed and implemented workflows for trade submission, settlement-window execution, net position calculation, liquidity management, and settlement validation. Improved security using OpenZeppelin components (SafeERC20, Ownable, ReentrancyGuard) with access control and state validation. Exposed ABI/RPC interfaces and on-chain dashboard metrics to support external integrations for netting/settlement statistics.
Blockchain Smart Contract Developer (Hackathon Project: Blockchain-based Netting Settlement System)
August 1, 2026 - Present
Built smart contracts for a blockchain-based trade netting and settlement system. Implemented Netting, Settlement, and Liquidity Buffer modules in Solidity using Foundry and OpenZeppelin. Designed and implemented settlement-window workflows including trade submission, net position calculation, liquidity management, and settlement validation. Strengthened security with OpenZeppelin patterns (SafeERC20, Ownable, ReentrancyGuard) and added access-control and state-validation logic. Exposed ABI/RPC interfaces and on-chain dashboard metrics to enable external applications to fetch settlement and netting statistics directly from smart contracts.
Development Position at Beijing Intelligent Token Technology Co., Ltd
July 1, 2023 - August 31, 2023
Developed interactive Unreal Engine scenes and gameplay systems using Blueprint and Python as part of a short-term development engagement. Contributed to building game-like experiences and prototyping gameplay functionality through scripting and engine workflows.
