What I'm looking for

I'm looking for remote freelance, B2B contract, part-time, or full-time work up to 40 hours per week, helping teams build cost-efficient cloud platforms, production MVPs, Kubernetes infrastructure, and reliable delivery systems.

At UMSCHOOL, I operate three Kubernetes clusters, more than 40 environments, and 50+ microservices. I built GitOps delivery workflows with GitLab CI and Argo CD, improving deployment speed, availability, observability, and infrastructure efficiency.

I help startups reach their first production MVP quickly while minimizing infrastructure cost. I design lean AWS architectures with Lambda, Fargate, or EC2, then evolve platforms toward Kubernetes when product growth justifies it.

Previously at EPAM, I designed and maintained CI/CD pipelines and enterprise delivery infrastructure for international projects including Bose.com. My work spans AWS, Azure, Docker, Kubernetes, Terraform, Ansible, Jenkins, Python, Bash, and Groovy.

Across 20+ years in IT, I've built and operated large Linux, networking, VoIP, automation, and monitoring environments at Fujitsu, Unitel, and ER-Telecom, supporting more than 200,000 customers.
