Hire the Best Apache Administrators
in Ukraine

Your server's down at 3am. Your cloud bill doubled. Deploys are a Friday nightmare. I fix exactly this — fast, with a rollback plan for every change. Results from 49 completed projects (100% Job Success): - 99.9% uptime — real monitoring with Prometheus, Grafana, and structured alerting - 30-60% faster page loads — Nginx/Apache tuning, CDN, TLS hardening, HTTP/2 - 20-35% lower cloud costs — right-sizing, autoscaling, lifecycle policies, FinOps - Deploys in minutes — Docker, Kubernetes, GitOps (ArgoCD/Flux), GitHub Actions, GitLab CI What I do: - Infrastructure & Containers: Linux, Docker, Kubernetes, Helm, Terraform, Ansible - Cloud: AWS, GCP, Azure - CI/CD: GitHub Actions, GitLab CI, ArgoCD, blue-green/canary deploys - Monitoring: Prometheus, Grafana, OpenTelemetry, ELK/OpenSearch - Security: Vault, SBOM/SLSA, Zero Trust, WireGuard/OpenVPN - Scripting: Bash, Python, Go, PowerShell How I start: 1. Quick audit (30-60 min) — what's running, what's breaking, what costs money for no reason 2. Prioritized action plan — what to fix now, what can wait, rollback strategy for every change 3. Early wins in 48 hours — faster response, fewer alerts, lower bill, working backups I don't do "two weeks of discovery." I dig in, find the worst problems, fix them fast. Tell me what's hurting — I'll be straight about whether I can help and what it takes.

As an expert System Administrator, I provide the best technical solutions for clients' business needs. I help choose the best architecture, deploy and configure it, or optimize an existing one - regardless of its size, from a single small Linux or Windows Server VPS to a complex workload in the AWS environment. My clients count on me for scaling, security, network administration, migrations, discovering and documenting existing infrastructure, and cost management. I also provide ongoing support with server management. I focus on the client experience and do my best to make it outstanding. My advantage is my cross-layer experience: • If a page takes 40 seconds to load, I can trace the problem through the application, web server, OS, network, database, and storage instead of guessing at one layer. • When I plan a cloud infrastructure, I consider not only AWS Well-Architected Framework, but also the application and OS fundamentals themselves. Combined with deep operational and business experience and the ability to learn unfamiliar systems quickly, this helps me build solutions that fit the actual business. A few examples: • Migrated a complex WordPress environment from Amazon Web Services to Vultr after 4+ months of failed attempts: used Terraform, Ansible, and Cloudflare Workers. The migration was completed in 1 week. • Reduced PostgreSQL query times from 40-80 seconds to 0.4-2 seconds on a 35 GB / 31M-record dataset: used query optimization, indexing, materialized views, and PostgreSQL tuning. • Reduced WordPress/server response times from 5-9 seconds to 0.8-1.2 seconds: fixed ModSecurity, MySQL, RAM pressure, and PHP-FPM issues. • Recovered a 5+ GB MySQL database with damaged InnoDB tables where there were no usable backups: used sysadmin magic and a bit of luck. I have a 100% Job Success Score and 5.0 rating on Upwork. After all, I prefer long-term partnership, so put the quality at the top.

More about me: I troubleshoot costs and performance using the scientific method. My IT management and customer support background let me prepare and apply changes systematically, test them, and keep a rollback plan. I work iteratively with planned changes, priorities, automation, monitoring and documentation.

I'm an experienced sysadmin, so you can bet on getting a reliable, hands-on Senior Systems Administrator for your tasks, a kind of infrastructure specialist. For automation and DevOps, I use Python, Bash, Terraform, and Ansible. I also work with WordPress, PHP, Nginx, Apache, cPanel/WHM, Plesk, and email infrastructure in Linux System Administration environments. For databases, I work with MySQL, PostgreSQL, and MSSQL, including performance tuning, indexing, migrations, backup and recovery, and troubleshooting across the application and infrastructure layers.
