Senior🎓
Top SchoolJi Kai is a full-stack engineer and serial founder with 11 years of experience building web and blockchain systems from Singapore. As Co-Founder of SOFA.org and former core DeFi developer at QuarkChain, he specializes in dApps and smart contracts across Ethereum and Tron, and has hands-on experience with crypto wallets and public chain development. He codes across Node.js, Python, Ruby, PHP, Solidity and SQL, with additional fluency in Java and C++, enabling him to move between backend, smart contract, and integration work smoothly. Earlier entrepreneurial ventures include multiple consumer and fintech platforms, reflecting a product-minded approach to engineering. Comfortable working in multilingual teams (fluent English, some Japanese) and trained at Zhejiang University with an exchange at Keio, he brings both startup grit and protocol-level expertise. An underappreciated strength is his breadth: he pairs low-level EDA/optimization experience with modern blockchain development, making him effective at bridging research-quality code and production systems.
