I'm a DevOps / SRE professional with 5 years of experience.
A big fan of IaC, troubleshooting and the SRE methodology.

Hi there! My name is Sergei, and I'm a DevOps / SRE professional with 5 years of experience. With my expertise, I've built, deployed, and managed systems on public clouds like AWS, GCP, and Hetzner Cloud. I like to think of myself as a cloud whisperer - I can make it do whatever I want!

When it comes to workload orchestrators, I've worked with Kubernetes and Docker Swarm, and I'm always up for a challenge when it comes to orchestrating containers. I've also helped organizations implement robust continuous integration and continuous delivery pipelines using GitLab CI, Jenkins, TeamCity, and Github Actions. If you need someone to automate your deployment process, I'm the one for the job!

I'm a big fan of configuration management tools, and Pulumi is one of my favorites. In fact, I've even written some code in Go and Typescript for Pulumi, which you can find on my GitHub profile.

Of course, I've also got other configuration management tools in my arsenal, including Terraform, Ansible, Puppet, and Chef. These tools help me keep everything in check, so I can focus on the fun stuff - like monitoring and logging. I'm a big fan of Prometheus, Grafana and Loki, and I can help you set up a monitoring and logging solution that will knock your socks off.

When it comes to being a SRE, I've got you covered too. I know how to handle production issues and the necessity of on-call duties. I'm no stranger to late-night alerts and critical outages, and I'm always ready to spring into action to get things back on track.

When I'm not busy automating all the things, you can find me tinkering with databases like PostgreSQL, MongoDB, and Redis, or writing code in languages like Go. By the way, let's not forget about web servers - I've worked with Nginx and Traefik, and I know how to make them sing!

So if you're looking for a DevOps expert or SRE who can make your cloud dreams come true, look for no one else than me. I'm the cloud whisperer you've been searching for!
