AWS Certified Solutions Architect|Cyber Security Researcher|CEH

I keep AWS and Linux servers fast, secure, and online. When something breaks, I get on it quickly and fix it properly instead of putting a patch over it. Most of my clients come to me because they cannot afford downtime, and they stay because things just work after I am done. A bit about my experience. I have spent the last 12+ years managing servers and infrastructure, with over 11,000 hours of it right here on Upwork. Some of the things I do most: Migrations. Moving websites and applications between servers, or onto AWS, with the lowest possible downtime. This is the work I enjoy most and the work I am known for. High availability setups. Load balanced web servers on Apache and Nginx, MySQL, Percona and MariaDB with master and slave replication, Varnish for caching, Bind for DNS, and NFS for shared storage. Security and compliance. Server hardening, firewalls, ModSecurity, and locking things down sensibly. I have worked on PCI requirements and I hold a CEH. Automation and monitoring. I use shell scripting to take care of the repetitive daily work, and I set up monitoring so problems get caught before your users ever notice them. How I work, and why clients keep coming back: I genuinely care about doing the job well, not just done. Your data stays private. I am happy to sign an NDA. I do not outsource. You deal with me directly, start to finish. I would rather ask a few good questions up front than guess and make a mistake. I explain things in plain language, whether you are a senior architect or not technical at all. Tools and tech I work with: AWS, CloudFront, Cloudflare, Linux (CentOS, Ubuntu, RedHat, FreeBSD), Apache, Nginx, Varnish, MySQL, Percona, MariaDB, Bind, NFS, server security and firewalls, ModSecurity, shell scripting, Nagios, and tuned setups for WordPress, Drupal and Joomla. Comfortable with cPanel, Plesk and Webmin too. I am around on weekdays and easy to reach over email, phone, Teams, Telegram or Google Chat, and I usually respond within a few hours. Happy to share references if you would like them. If you have a server that needs moving, securing, speeding up, or rescuing, send me a message and tell me what is going on. I will tell you honestly whether I can help and how I would approach it.
