When production breaks, you need an engineer who knows how things actually work. I'm a veteran DevOps / Site Reliability Engineer specializing in complex production problems, emergency troubleshooting, performance optimization, and infrastructure architecture. I LOVE DIFFICULT PROBLEMS. ESPECIALLY THE URGENT ONES. Servers crashing under load? Websites painfully slow? A deployment gone wrong? A compromised server? Cloud infrastructure costing far more than it should? I investigate, identify the root cause, and fix it. Not just the symptoms. I work across the entire stack — from application code and database queries to Linux internals, networking, cloud infrastructure, and deployment pipelines. This allows me to solve problems that fall between the responsibilities of developers, sysadmins, and cloud engineers. WHAT I DO BEST 🚨 Production emergencies & incident response Outages, crashes, performance degradation, security incidents, broken deployments, and complex failures. ⚡ Performance engineering High-traffic websites, WordPress, Magento, PHP applications, MySQL/MariaDB, Nginx, caching, database optimization, and bottleneck analysis. ☁️ Cloud architecture & cost optimization AWS, Google Cloud, DigitalOcean, and other providers. Scaling, restructuring, and eliminating unnecessary infrastructure costs. I've saved clients thousands of dollars. ⚙️ DevOps & automation Terraform, Ansible, Docker, Kubernetes, ECS, GitLab CI/CD, GitHub Actions, and reliable deployment pipelines. 🔄 Complex migrations & modernization Moving applications, servers, databases, and email systems with minimal disruption. Bringing legacy infrastructure up to modern standards. 🔒 Security & reliability Server hardening, Cloudflare WAF, SSL/TLS, incident investigation, monitoring, backup and recovery strategies. 🔍 Deep technical troubleshooting Issues that require reading source code, tracing system behavior, analyzing logs, understanding protocols, or investigating unfamiliar software.

My engineering background goes far beyond conventional DevOps. Earlier in my career, I spent 11 years specializing in data recovery, reverse engineering, and low-level systems programming, developing tools in C, C#, and Python. That experience shaped how I approach engineering: I don't blindly follow tutorials or apply generic fixes. I investigate how systems work, understand why they fail, and develop solutions appropriate to the actual problem. AI can generate configurations and deployment scripts. Making complex production systems secure, fast, reliable, and cost-efficient still requires engineering judgment. I embrace modern tools and automation, but I don't confuse generated code with verified solutions. Need to rescue a failing system, solve an elusive technical problem, or build infrastructure that will actually scale? Let's talk.
