I am a software engineer based in Tokyo. I was born in northeast China and moved to Japan. I work mostly on backend systems, blockchain, and crypto, and most of my code is on GitHub as @dongri.
Photo-sharing app where every post is minted as an NFT and listed on OpenSea, with passkey login and a non-custodial wallet.
LGTM image service for code review, running since 2016 and continually rebuilt as a playground for whatever is new on the web, from browser extensions and open APIs to AI agents and on-chain payments.
A tiny, unfunded playground for fully on-chain NFTs, tokens and apps on Ethereum and its L2s. Art, metadata and logic live in the contracts themselves, with open minting and no dependence on any server, so everything keeps working even if the front-end disappears.
A personal lab where ideas get built the moment they come up and shipped as they are, rough edges included. No roadmap, just small experiments that keep growing in number.
