Solving IT problems for🎖️17+ years. On Upwork: 300+ hours, 6K+ earnings. Lower rates until I reach 9 reviews (5-star). Quality work normally paid at ~$30/hr only NOW available at reduced price. Don't wait until that last 9th review. I value customer satisfaction & robust solutions. Why? Because I can have more spare time and enjoy it later. Welcome! You need your problem solved and I can probably help. Probably. I know the struggle. Looking for a solution or a professional to do a task that is not exactly your expertise. Making fast and right decisions, because everybody counts on you. Trying to fit into the budged. Sudden change of plans. The long hours. The new unexpected task. A half-working solution. Back to the drawing board. The deadlines. The fluctuations in revenue. The customers! How do I know? I've experienced it while I was managing the day to day operations of my own escape room business for 8 years. And additionally working in IT for full or half day as a daily job. That is how I know. That is why I will not waste your time. ✅ I will do my best to solve the issue if I can. ✅ I will not promise things I am not 90% certain are possible. ✅ I will consider the solution which is most beneficial for you from technical and financial perspective. ✅ I usually look for the root cause of the problem and try to fix it once and for all. ✅ Often I had found ideas for solving many clients issues just by having a discussion. What is my expertise? ✅ I will never compromise with security for a bit of user convenience. ✅ I will NOT leave a half-finished solution in the middle. Unless you are not paying the work done. ✅ Free and open source software are a major interest. I have more the 17 years IT experience and I have held different positions in the field. Close to the entire spectrum. You can check my employment history (before Upwork) on my profile. Still, GNU/Linux (a.k.a simply "Linux") system administration stays my favorite one. ✅ I have more than 20 years of experience on the GNU/Linux (a.k.a. just "Linux") command line. ✅ I have close to 10 years with cloud. ✅ I have more than 5 years in DevOps. I have experience with different cloud and hosting providers: ✅ Digital Ocean ✅ Hetzner ✅ Google Cloud Platform (GCP) ✅ Amazon Web Services (AWS) ✅ Namecheap ✅ Vultr ✅ Infomaniak ✅ Linode ✅ OpenStack (I was public cloud system administrator) I've implemented CI/CD in several YAML dialects and know other automation tools as well: ✅ Github Actions ✅ Gitlab CI ✅ Jenkins ✅ CircleCI ✅ Bash shell scripts ;) (before CI was a thing) ✅ Ansible (Infrastructure as Code / IaC; server automation) ✅ Cron / systemd timers ✅ Python ✅ Perl I've used distributions like Slackware, CentOS, Gentoo, Trisquel, Ubuntu and Debian. The last (three) are preferred. So, are we doing a project? Send me a message or an invite and let's get started. P.S. Don't forget to check my project catalog as well.
