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.
