I will skip the hero section and tell you directly what I can do for you: • stable deployments that don’t break on Fridays • consistent, reproducible environments (no more “works on my machine”) • clean CI/CD pipelines with fast, reliable builds and deployments • zero-drift infrastructure with clear IaC discipline • fewer incidents and faster recovery when something goes wrong • simple, maintainable setups with clear documentation • a platform the whole team can trust and build on • faster onboarding for new engineers (everything predictable, documented and automated) • disaster-recovery flows that actually work (Btrfs snapshots, backups and reliable restore paths) • smoother day-to-day operations so your team focuses on building, not firefighting Hi — you’re still here? Thank you. If this resonates with you, we’ll be a good fit. Let’s talk. 11 successful Upwork projects and counting — 5★ reviews and long-term clients. Here are more details about my work — I know you want to know more about me. I follow best DevOps practices to build stable cloud infrastructure using Containers (Docker, Docker Compose), Kubernetes (Rancher, K3s, RKE2, MicroK8s), Infrastructure as Code / IaC (Terraform, OpenTofu) and CI/CD (GitLab CI/CD, GitHub Actions, Rancher Fleet) — deployed on AWS, GCP and Hetzner Cloud. With 20+ years of engineering experience, I deliver clean, reliable and reproducible environments that behave consistently under load. My work spans greenfield builds, modernization of legacy systems and stabilizing fragile or inconsistent environments by improving architecture, tightening IaC discipline, restructuring Kubernetes workloads and enforcing clean CI/CD patterns. What I work with: • Kubernetes (Rancher, K3s, RKE2, MicroK8s, GKE) • Infrastructure as Code / IaC (Terraform, OpenTofu — clean, reproducible infrastructure) • Containers (Docker, Docker Compose) • CI/CD (GitLab CI/CD, GitHub Actions, Rancher Fleet) • Legacy monoliths, VMs, custom setups → containers / cloud migration • Observability (Fluent Bit, Stackdriver, GCP Logging, monitoring, alerts) • Environment design (dev → stage → prod, automation, separation, promotion flow) • Troubleshooting hard-to-reproduce infrastructure issues I expect every client to bring a slightly different stack and workflow. That’s what keeps this work interesting. If your tools aren’t on this list, that’s completely fine. I’m always ready to adapt, learn, and grow with you through real project work. Here’s a bonus for the end — because if you’ve read this far, you’re clearly a patient person. I don’t start with AI, LangChain, RAG pipelines, vector databases or any other buzzword stack, because I don’t want to attract the wrong crowd. The truth is, AI is not the foundation. It’s just a layer your developers will build on top of stable infrastructure. That’s where I come in. And after 20+ years in different roles — from junior coder to Head of Software Development (CTO-level responsibilities) — I know how to build a platform that makes every layer above it stronger, including AI.
