    Projects

    Real Estate Blockchain Project

    Consultant
    2024/03 – Present
  • •Worked on an RWA project where the team implemented a combination of CDP, AMM, and tailored pricing curves to optimize slippage and stabilize asset pricing.
  • •I contributed by integrating oracle feeds and helping develop the backend logic and smart contracts to ensure the AMM stayed tightly aligned with real-world asset values.

    • HFT & MEV Project

    2022/08 – 2023/11
  • •Built a high-frequency trading (HFT) platform optimized for low-latency execution, real-time market data processing, and high-throughput strategy evaluation across DEXs such as Uniswap and Balancer. The platform was developed in Rust for maximum performance and deployed on AWS.
  • •Created a Rust-based MEV sandwich bot deployed on AWS, functioning as a searcher to identify arbitrage opportunities and submit bundles through Flashbots. The project began with a TypeScript implementation before being migrated to Rust for improved speed and memory safety.
