Most recently, I am working on Dbux, an advanced Intregrated Debugging Environment for VSCode (see below for details). I have written several single-page web applications that I (and few others) have been using with students in classes using JavaScript and Node, as well as Angular and (more recently) React. In one project I used Node with Express and MySQL with sequelize on the backend, and Angular on the front. I wrote a middleware "NoGap" which provides RPC, basic asset management and, most importantly, code sharing capabilities to allow more rapid prototype development and simplified Client/Server communication. Built several web app prototypes using React + Firebase. When I got bored with that, I started digging deeper to produce a library using Proxies to more easily model Firebase schemas and bi-directionally databind Firebase (as well as local cache) data into React components. Used HTML5 streams to record videos, and HTML5 filesystem as well as the YouTube API to record, queue and upload entire batches of videos using only very few button clicks. Reasonable experience in performance optimization; several of my StackOverflow answers discuss performance problems in JavaScript, including object pools as well as "The fastest way to iterate over an object's properties in JS". Integrated Mediawiki with an Angular web application for "collaborative/competitive problem writing + solving" in university classes.

Used React in several of my JavaScript web application projects where I digged deep to figure out many of it's quirks, as well as common and not so common programming paradigms. I'm particularly interested in databinding: the problem of making it as simple as possible to display and write remote data in a React component which is why I wrote my own DBDI (DataBinding via Dependency Injection) library to easily display and write Firebase, local cache and generally, any remote API (e.g. YouTube API) data.

C# was one of the first languages I used, along with Java. I worked on many small Game server and client projects from 2000 to 2010, mostly for Ultima Online and World of Warcraft. Recently I used C# for developing game features and small game projects in Unity.

Implemented many game features and mini game projects in Unity. Used Unity to help students (middle school to university) try out programming and game development. Of over a hundred features that I have written, here are a few that I built in a two week rapid prototyping marathon: http://bit.do/some-unity-prototypes (with notes and explanations in Chinese)

Java was one of the first languages I touched back in 2000. Been using it in for several projects and several jobs, including a "File Upload Applet" (back in the days, browsers weren't quite that good at handling those) and a music sharing Desktop application.

Built some (very basic) 3D game prototypes. Integrated the Bullet physics engine with the open source CrystalSpace game engine for GoogleCode 2012. Worked on NVIDIA's CUDA libraries team (Santa Clara/Silicon Valley) during an internship in 2013.

Used CodeSignal and Leetcode to practice Python and better understand how to effectively and quickly solve commonly occuring problems in programming, algorithms and data structures. I also did some workshops on Python basics, web scraping and data visualization basics.
