    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! :)

    I have 12 years of System Administration experience, in companies providing outsourcing services to Fortune500 enterprises around the world. What can I do for you: - migrate all kind of sites (from Wordpress to more complicated) to Amazon AWS, Ovh.ie, DigitalOcean, and any other providers. - configure various AWS Services (Ec2, CloudFront, RDS, Aurora, S3, SES, SNS, etc); - perform any kind of administrative work on your Linux Servers (install software, configure services, setup backups, etc); - create any kind of automations; - write scripts in Bash, Perl, Python; - configure monitoring systems using Nagios. I know how to install/configure/code: Web: apache, nginx, haproxy. Can recompile if needed, can install and compile modules. DB: Mysql (proficient), SQL Server (proficient), PostgreSQL (moderate). Programming Languages: Perl, Bash, PowerShell, JavaScript, Python. Monitoring Systems: Nagios (and derivatives), munin, monit. DNS: any system. Email: sendmail, exim, postfix. Hosting Panels: cPanel, Directadmin, VestaCP, ISPconfig. Virtualization: Amazon AWS - expert. Any other - can do. I'm an excellent learner, for a task I learned PowerShell in 5 hours (sufficient enough to make a pretty complex automation). For another task I learned JavaScript in 8 hours (sufficient enough to make a great Google Apps Script automation). It took me 3 days (24 cumulated hours) to learn Python. So if there is a technology not listed here, I either know it but didn't list, to save space, or I can learn it very quickly.

    First thing off: I DON'T USE SKYPE (and other proprietary closed protocols and technologies: teamviewer etc.), but I have mail, jabber and jitsi. ✓ UNIX. Portable programming (C-99, POSIX, autotools), portable shell programming (POSIX.2) — dealt with many subtleties in different implementations. System programming. Embedded. ✓ My primary language is python now (see my Scripting profile). Currently learning django, ansible. I work fast, if in doubt, ask for the time estimate, beware, communication may take twice the time spent on coding, so it's always best to make up your mind before hiring! I'm honest, reliable and tenacious, and I don't remove bad feedback (enjoy!:) Lifetime warranty for my work (doesn't include new features though). The list of capabilities is not full, as I've experience ranging from Jenkins to writing parsers with lex/yacc, from IP traffic handling in C++ (libnetfilter_queue plus iptables custom kernel module) to product installers. I use Gentoo and EMACS. I'm easily searchable, and if you want, you can find any information about me outside of upwork. Aquila non captat muscas. Usually. But my rate effectively cuts off the stuff that everyone can do:) Also you may consider my agency (Laguz d.o.o.), there are junior programmers whom I supervise and ensure the work done. Should be about the same quality for a fraction of price. NB. If you want me to use some collaboration tools, usually it won't work. Few mail servers on Earth support my email, most of the time it's impossible for me to register.
