Hi! I'm Teoman. I currently work as a full time DevOps Engineer for the Ministry of Interior. My main responsibilities include: - Managing Kubernetes Clusters that vary from development, staging to production. I also hold the CKA certificate. The applications run on the cluster are Java microservices, infrastructure related applications such as internal packaging systems (plugins, image registries), deployment related applications such as ArgoCD and GitLab runners and so on. I manage Big Data Engineering Kubernetes clusters that host Spark Applications, NiFi clusters, Trino backends, etc. - GitLab CI/CD pipelines where as a DevOps team, managing more than 50 projects and tracing every pipeline 24/7, creating smooth deployments that are being used by the whole country. - Managing infrastructure as code where I make calls affecting hundreds of Linux servers including production servers, tracking changes with Git. - Monitoring the running infrastructure where this many servers need to be intervened immediately in case of any failure, in which I rely on Grafana Prometheus Loki stack which again deployed on Kubernetes and bare metal, with many instances running on many networks collecting logs and metrics. I'm a Linux user since 16, and a professional administrator for 3 years now. Would be glad to be of your service, Thanks

As a Cloud & DevOps Engineer, I help companies build reliable cloud infrastructure, DevOps platforms, infrastructure automation, and highly available systems using AWS, Kubernetes, Terraform, CI/CD, and modern security and monitoring practices. Today, I also help teams adopt AI-assisted development tools, including Claude Code and automation agents, in a practical, secure, and production-ready way. Modern DevOps is no longer only about infrastructure, pipelines, and servers. Teams are now building faster than ever with AI coding assistants, autonomous workflows, and vibe-coding tools. But fast AI-generated prototypes often need expert cloud, DevOps, security, and architecture work before they can become stable production systems. This is where my 20 years of hands-on IT experience, recognition by Upwork as an Expert-Vetted professional, and being featured in Upwork's Success Stories become real advantages. I am also the author of The Cloud DevOps Engineer's Guide, where I showcase the proven methodologies I apply to help organizations design, automate, secure, and scale resilient, cloud-native infrastructures. My core expertise includes: ✔️ Cloud infrastructure on AWS, Azure, GCP, and DigitalOcean. ✔️ Kubernetes, Docker, Helm, and production container deployments. ✔️ Terraform, Ansible, Infrastructure as Code, and environment automation. ✔️ CI/CD pipelines with GitHub Actions, GitLab CI, Jenkins, and other tools. ✔️ Claude Code, OpenClaw, and AI-assisted development workflow adoption. ✔️ AI-generated and vibe-coded application review, stabilization, deployment, and scaling. ✔️ Large codebase navigation, refactoring support, and development automation. ✔️ AI-assisted test generation, documentation workflows, and code review support. ✔️ Security reviews for code, cloud infrastructure, secrets, permissions, and deployments. ✔️ Custom AI agents for engineering, DevOps, monitoring, and code review workflows. ✔️ 24/7 monitoring, observability, alerting, logging, and incident-response automation. ✔️ DevSecOps, secure pipelines, automated checks, and production hardening. ✔️ Cost optimization, scalability, reliability, and high availability. ✔️ Linux, Bash, Python, networking, databases, distributed systems, and cloud-native architecture. My experience across AWS, Azure, GCP, Kubernetes, Terraform, Docker, CI/CD, monitoring, and security allows me to work not only as a DevOps Engineer but also as an AI-Augmented Platform Engineer, helping teams modernize how they build, deploy, review, secure, and operate software. Whether you need to modernize your infrastructure, adopt Claude Code, explore OpenClaw-based automation, build custom agents, review an AI-generated codebase, stabilize a vibe-coded application, or deploy, secure, and scale your prototype in the cloud, I can help you move from idea to production with a secure, stable, and scalable setup.
