Because there is no substitute for experience.

15+ years of Linux system admin and DevOps experience including but not limited to system scalability and performance, security auditing and hardening solutions, database architecture and administration, networking, advanced Bash, Puppet, Perl, Python and PHP scripting, problem-solving, virtual computing solutions, high availability systems, etc. Have a keen eye for detail. Every job is always done with absolute care, high ethics, and full responsibility. Also, strong language skills (speed reader, decent proofreading abilities, broad vocabulary), bilingual (Polish and English), able to deliver top-notch, 100% manual translations, and never using any sort of automated translation tools in my work. I have enjoyed working on various docs, brochures, user guides, articles, blog posts, (e)books, theses, websites, videos, mobile games/apps, and software products. To date, I successfully delivered content for numerous brands, organizations, and companies, including, but not limited to: Johnson & Johnson, Lidl, Auchan, Subway, Kiwi, TripAdvisor, Emirates, eToro, Ubisoft, Microgaming, Playtech, SweTrack, Combilift, Lockheed Martin, Boston Dynamics, Intel, and more. Always working alone. Never outsourcing my jobs. Never passing any credentials, content, or other data to anyone. My motto: "It always seems impossible until it's done." ― Nelson Mandela
