    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.
