About & Projects
Full-stack developer at @microsoft by day, indie creator by night, and a cool dad always.
I started in competitive programming (NOI ‘08, ‘09 in China), where I learned to enjoy coding and building cool stuff. Now, I spend my time building apps, games, and compilers.
I also translate tech materials and write short stories.

WeWord
AI-generated dictionary, thesaurus and crosswords
WeWord is an AI-generated dictionary, thesaurus and crossword puzzles.
It helps to see how the AI sees our world by letting it explain our language.
fiber note
a bi-directional networked note-taking app
fiber-note is a bi-directional networked note-taking app which is open and self-hosting, inspired by roam-research, obsidian and others.
I’m working on a series of dev diaries around the building of fiber-note:
ruby on rust
An implementation of ruby in rust
ruby-on-rust is an implementation of 
ruby language in pure 
rust, consists of (barely working) lexer and parser, and a WIP interpreter.
I started this project as a way to learn rust. Eventually, I’ve learned more than that, including lexer & parser, ragel, and a lot of ruby’s hidden magic.
Lots of the grammar rules and AST conventions are ripped from the parser gem. For lexer, I adapted some rules from parser and ported from ragel-6 to ragel-7. For parser, I use syntax-cli as the parser generator.
references.wiki
tracking pop culture references
I watched/played so many tv shows/video games that I have to build references.wiki to organize and visualize pop culture references between tv shows, video games, fictional characters, etc.
I composed scrappers to fetch and parse the occurrences of pop culture references in different wikia (fandom) sites. Currently I’ve parsed around 5000 references between 1000 works/celebrities.
I built my own knowledge base to cross-reference sources like wikidata, google kg, and wolfram alpha. I implemented a customized editor for user to create new references between works.
The next step will be UGC workflow (I’m considering a git-based one), editing history and data visualization.
project yoru
visual novel generator
Project yoru is a set of projects to build cross-platform visual novel games from only assets and scripts, without coding.
To build this project, I was using polymer, lots of gulp scripts, phonegap build, which are all practically dead by now :|
