Vadym S.

I am a Senior DevOps Engineer with over 10 years of experience designing, automating, and managing production infrastructure for enterprise software, SaaS platforms, and blockchain applications. I am a **Certified Kubernetes Administrator (CKA)** and a **Red Hat Certified Engineer (RHCE)** with extensive expertise in Kubernetes, Linux system administration, GitOps, CI/CD automation, and Infrastructure as Code. I design and maintain scalable, highly available infrastructure on AWS and on-premises environments using Terraform, Ansible, Docker, Kubernetes, NGINX, GitHub Actions, Argo CD, and other cloud-native technologies. In addition to DevOps, I am also an experienced software developer. I work with **Python, Go, JavaScript/TypeScript (Node.js, React), PHP, and Perl**, allowing me to bridge the gap between development and operations. I build automation tools, REST APIs, backend services, deployment platforms, CI/CD pipelines, and developer tooling that improve productivity and reliability. My experience includes: * Kubernetes cluster architecture and administration * GitOps with Argo CD * CI/CD pipelines with GitHub Actions * Infrastructure as Code with Terraform and Ansible * AWS cloud architecture and automation * Docker and containerized applications * Linux administration (Red Hat, Ubuntu, Debian) * NGINX, HAProxy, and reverse proxy solutions * Monitoring and observability with Prometheus, Grafana, and Zabbix * PostgreSQL and MySQL administration * API development and automation with Python and Go * Blockchain infrastructure and distributed systems I enjoy solving complex infrastructure challenges, automating repetitive tasks, and building reliable platforms that enable development teams to deliver software faster and with confidence. Whether you need a complete cloud infrastructure, Kubernetes migration, CI/CD implementation, Linux administration, backend development, or custom automation, I can deliver production-ready solutions tailored to your business.
