Pwning teh internetz since 2007

I love interesting & crazy stuff, clean reusable code, maintainable scalable hi-load architectures, shells, vim, tmux, awesomewm, drones, IoT, Doom game series, UT99, multiplayer game hacking, OpenSource, heavy/thrash/stoner metal, traveling, motorcycles (I own a Honda Transalp 700/2009), snowboarding & random adventures.

I like to pursuit fresh ideas, to be precise in my profession & to be verbose in communication.

I've been coding for around 12 years and experienced a lot of technologies. My belief is that every task requires a specific set of tools and technologies in order to be solved efficiently. That's why I often switch mainly between Python, JS, C, Java and Go (sorted by experience.)

I refactored existing internal dial plan management system that used asterisk SIP (Asterisk) and which handled over 1,000,000 phone calls a month. I eliminated existing memory usage issues & file descriptor (that were initially caused by abusing threads) leaks which allowed us to run the server continuously for months without having to restart it every 20 minutes as before. I also developed a fork of "Twinkle" SIP client (written in Qt) that we called "Sparkle". It was using a modified & simplified UI and gave the operators more control over their calls.
