Hello. This is my personal website. Calm down, I will not know, let alone be angry, if you are finding my personal information on this website. :)

About me

I’m a former student in Tongji University, Shanghai, majoring Software Engineering (it’s almost equivalent to Computer Science if you are outside of Mainland China). My interests include Ruby, compiler engineering and building interesting apps. I graduated at July of 2019.

Normally, I use a green star, originally a symbol for Esperanto (although I don’t know Esperanto even for now), as my icon across internet. (I know that’s impressive!) And I use ecnelises as my username, produced by reverse the word ‘silence’ and put ‘es’ after it for pluralizing.

About work

Now I’m working for IBM China Systems Lab as a software engineer. My work is about LLVM-based C++ compilers, especially IBM POWER target-specified backend optimizations. I’ve became part of the team since January of 2019.

I was a participant of Google Summer of Code 2018, for the Ruby organization. During the GSoC summer, I added multi-factor authentication feature to both site and RubyGems tool.

For approximately second half of 2017, I have worked as backend internship for Strikingly, a great tool for non-geek people to build their own websites, miniprograms and games.

I was also a co-founding member of Tongji Open-Source Students Association (previously known as Tongji Computer Association, TJCA). The organization currently maintains Tongji Open-Source Software Mirror.

About this site

I have a blog for my thoughts, more than category of technology, at, articles on it are usually in Chinese.

Another site hosted by GitHub Pages is also actively updated. They are in English. Now my GSoC reports are on it, but I may update other articles about programming.

I have also write serveral pages for easy online PGP crypt, see PGP. Nothing will be recorded.

For generating your own idenicon from arbitrary text, see Idenicon, that’s interesting.
