    Programmer / Developer

    Russia - Last active: 3 months ago - Tests: 9

    I'm awful at selling myself, it gave me a headache just to write this text. Someone called me a superstar, when I passed the screening process for a Python developer position, to this day I still laugh about it. No, I'm not bad by any means, I'm probably better than average, but I'm certainly not Guido or Armin Rigo. My skills and experiences, I have a wide range of those, from your typical web development to computer vision and genetic algorithms in context of game development, but most of it is on the jack of all trades level, definitely not an expert. I suppose my forte is Python backend development, but I've done frontend work as well (AngularJS). I'm currently trying to get into MEAN stack, since it seems to be popular nowadays. As for workflow and methodologies, I double check my commits and try to write the code as clean as possible, I follow TDD when possible, and prefer an uncluttered text editor and terminal tools as my IDE.
