    Ever since I was a kid, I've been fascinated by computers. I was introduced to Linux almost 15 years ago, and that was the time I discovered my first true passion.. I worked as a software developer (iOS - Swift) and Linux system administrator, but I wasn't satisfied with neither developing corporate/commercial applications, nor repeating same routines like adding/removing users, setting up VPSs, configuring programs following the same conventions.. I needed something to satisfy my passion for creativity and problem solving/algorithmic/programmatic thinking, but that is still related to Linux.. Enter Bash, an amazing way to interact and utilize full potential of your Unix OS in a totally programmatic manner.. I've been perfecting my Bash skills for over 5 years now, and I have quite a lot of complex projects, successful jobs and happy clients to support that.. I'm also quite proficient with Python as well, but given my stand on mainstream appliances, I'm only interested in jobs utilizing core principles, I DON'T have any "domain-specific" skills, so please DON'T contact me about AI/Machine Learning/Trading/Full stack/bot automation etc, only basic python skills.. That being said, if you're looking for a Linux expert who thinks of Bash as a programming language and vim as an IDE, feel free to reach out and I'd be happy to provide my services! :)
