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! :)

If your website is critical to your business, security and stability aren’t optional - they’re infrastructure. I work with companies that rely on WordPress and WooCommerce in production environments, where downtime, attacks, or misconfigurations directly impact revenue. With over 10 years of experience in WordPress, Cloudflare, and Linux server environments, I typically get involved in situations where things need to be handled properly - not patched temporarily. What I focus on: • Advanced malware remediation and full-site recovery • Cloudflare architecture, WAF tuning, and traffic control • Bot mitigation and DDoS protection at scale • Linux server hardening and performance tuning (Nginx, Apache, MySQL) • Stabilizing high-traffic WooCommerce environments • Full-stack performance + security alignment I approach every project from both sides - application and infrastructure. That means understanding how WordPress behaves under load, how traffic is filtered at the edge (Cloudflare), and how the server handles what gets through. This is where most setups fail, and where I usually step in. I’m a Top Rated Plus freelancer on Upwork with a 100% Job Success score, and I’ve worked with 150+ clients across hundreds of production websites, many of them long-term. I don’t rely on generic solutions or one-size-fits-all setups. Every system is different, and I take the time to understand what’s actually happening before making changes. If you’re looking for someone who can take ownership of security and stability, not just fix isolated issues - we’ll likely be a good fit. ✔ Fast response (usually within a few hours) ✔ Available for urgent fixes (including hacked or down sites) ✔ Careful work on live environments (no unnecessary downtime) ✔ Root-cause fixes, not temporary patches
