More than a coder, more than a designer.

My name is PuiMan Cheui, a.k.a Aleen, who is living in Guangzhou, Guangdong, China mainland. My major post focuses on front-end developing with around 6 years of experience. The current primary task in the open-source world is to build up my note, PersonalWiki, progressively during my spared time with GitBook. At the same time, I maintain some GitBook tutorial plugins like gitbook-treeview, gitbook-footer, gitbook-comments (for integrating comments with GitLab and GitHub), etc.

• 🔭 I'm currently working on @Coremail (a.k.a @Mailtech, 2017 - Now). Previously on:
  • @Soundtooth (2015 - 2017)
  • @Monsoon (2014 - Now)
• 🏸 I'm currently learning how to play badminton and swim better.
• 🕹 Technical Stacks: JavaScript(TypeScript) + Babel + UglifyJS, Webpack, Gulp / Grunt, Less(Sass) + PostCss, core-js(shim), Handlebars, Karma / Jest, Puppeteer / Selenium, Eslint, etc.
• 🎮 Framework Experiences: React, Vue, Ionic + Angular 1.x, aralejs, etc.
• 😈 Compatibility Skill: DOWN to IE8! I have collected some confusing problems, and contributed to MDN at the same time.

Recently, I have brought out some TC39 proposals like proposal-object-pick-or-omit and proposal-promise-uncaught. It should be my pleasure to invite you to focus and discuss it to help to step more forwards stage 1 in the committee.

During the process of becoming an advanced JavasScript developer, I also hope to explore my graphic techniques in the future like WebGL, GLSL. To step out, I have written a small thing, named "How to draw in JavaScript", where we can use JavaScript to simulate drawing with given images.

As a coder, I also hope to be more than a designer at the same time, like creating "Mingtocat", or "Kaleidoscope".

Finally, appreciate your viewing of my profile! You can follow me if my works are of interest.
