English level: fluent
Years of experience: 11

Two achievements I value most:

1. I have developed and implemented transition of services from Xen virtual servers to clusters of OpenVZ containers long before Linux containers became mainstream technology. By tuning OS memory overcommit and OpenVZ memory settings I have been able to decrease costs of running bare metal hardware 3 times, because transition allowed to run 3 times more client services on same hardware.

2. I have been engaged in helping with one of the busiest Magento websites in the world. It was running on AWS. I suggested changes to Redis server configurations, TCP stack settings on EC2 instances and configuration changes to Percona XtraDB cluster. These allowed to increase application throughput in 2.5 times.
I came to Linux and OSS world out of curiosity and few years later my hobby became a profession. Since then, I have been working with Linux based server infrastructures and open source software in software development companies for more than decade already and have been doing SRE/DevOps most of this time, well before these terms even came to existence.

Over the last few years I have been working as Site Reliability Engineer / Linux Systems / Cloud Infrastructure expert around helping clients with resolving infrastructure related application performance and reliability issues, prepare and implement application migrations from premises to cloud, build and improve Kubernetes based microservice app oriented infrastructures, CI/CD pipelines and monitoring.

Looking for a project where I could meet my experience in solving issues with new challenges and enrich it. I'm pretty good in building/improving/managing Linux server infrastructures but want to become better. Looking for remote full time long term contract or relocation to US.
I am particularly interested in cloud/hybrid infrastructures, Kubernets / Hashi Corp stack, Terraform, Python/Golang, GitOps.

I can work well in startups as well as in corporate environments, as long as I work with smart people, using Linux and open source software and tools.

I don't do anything Microsoft.
