about me.
Hi, I'm Richard. I build websites and apps — the parts you click on, the code that runs behind them, and blockchain (web3) features too. I've worked on big shopping apps, games, and crypto products. I studied at Tsinghua University, I speak three languages, and right now I'm building my own startup, Solder. Want to make something cool together?
