Project history
* Created a cross-chain protocol between EVM and non-EVM chains using LayerZero to trade and generate
12% annual profit
* Wrote large portions of Rust's original green-threading runtime, and ported the entire runtime from C++
to Rust
* Developed the core smart contract of an Initial DEX Offering (IDO) crowdfunding platform using Solidity,
resulting in raising $1.5 million in funding within the first month.
* Built the platform's frontend with Web3.js and TypeScript to provide a user-friendly and seamless
crowdfunding experience to 1,000+ investors
* Led a team of 5 developers in the successful delivery of a large-scale e-commerce platform, resulting in
a 30% increase in online sales within the first quarter and able to use continuous integration and
distribution pipelines to deploy applications
* Worked for a fast-growing startup building Hybrid Consensus for Layer 1 blockchain in collaboration with
some of the world's top PhDs
