Since 2006, Hayk's been working as a full-stack developer with a myriad of tech and languages. Currently, his forte is HTML5 Canvas for front-end wizardry and Node.js for back-end magic. He also has a creative background—an appreciation for design which allows him to execute layouts down to the pixel. Hayk's also worked as a senior QA engineer which helps him think about testing as a fundamental part of the development process.

A small game for a competition called "ashugh" that can be found at Ashugh.com.

In that game, I created a tiny particle system to control the fireflies so that they could be used to indicate gameplay elements.

I decided to open-source the Firefly code by rewriting it, i.e., adding more configurable options and improving it along the way.

A demo of the actual code attached can be found at haykokoryun.github.io/fireflies/
and the GitHub repository is at github.com/HaykoKoryun/fireflies.
