Sergei Chukh

SRE / DevOps engineer

Hi there!
I'm currently based in Thailand and open to DevOps / SRE opportunities that include visa and work permit sponsorship.
I have hands-on experience with Kubernetes, GCP, AWS, CI/CD, and infrastructure as code.
I have nothing against "legacy" projects, as long as they generate revenue
