    17+ years of linux system admin and 3+ years of 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 and responsibility. Also, strong language skills (speed reader, broad vocabulary, excellent proofreading abilities), bilingual (Polish and English), able to deliver top-notch, 100% manual translations. I have enjoyed translating various docs, books, brochures, articles, websites, videos and software products. Never using any kind of automated translation tools in my work. Always working alone. Never outsourcing my jobs. Never passing any credentials, docs or other data to anyone. My motto: "It always seems impossible until it's done." ― Nelson Mandela méně
