Summary

Senior DevOps engineer with 7 years in infrastructure and 4 years of backend development before that. I build and run AWS and Kubernetes platforms with Terraform, with an SRE focus: observability, alerting and on-call. Coming from backend is my strong side: I can debug applications, find issues and create Pull Requests with changes right in application code.

Infrastructure: AWS (EKS, Lambda, Step Functions), Kubernetes, Helm, Karpenter, KEDA, Terraform, Docker
CI/CD & observability: Jenkins, VictoriaMetrics (Prometheus-compatible), VictoriaLogs, Grafana, Grafana OnCall, Sentry
Languages: Rust, TypeScript, Groovy, Bash

I love everything about DevOps, automation and stability. I build local development environments for backend developers that are comfortable from the very start (I was one of them), and I can (and do) wrap everything in a container, even GUI applications (sometimes it's easier than resolving dependency issues).

I've worked in Scrum and Kanban teams. I ask a lot of questions before starting: I'd rather clarify every detail up front than redo the work later (sometimes to the point of being a little annoying). I love working in a team, sharing my knowledge and gaining wisdom from more experienced people, and I enjoy peaceful holy wars over tech stuff with my colleagues.

I have Linux on all my devices. When my boss gave me a MacBook, I asked if I could install Linux on it. He said "No" and gave me an HP. I'm not a Linux maniac, it's just the most comfortable OS for me.

Languages

  • Russian Native
  • English Conversational (B2; Thanks YouTube)
  • Local language Ready to learn if I relocate

Personal Life a little about

Some of my current hobbies:

  • Music. Guitar and Piano playing. Singing sometimes. And (of course) listening. Graduated from music school class classical guitar;
  • Blogging about everything. Not only about work;
  • Programming. Yes, even after work. I really love Rust :crab: and use it in all my personal projects.

I've been happily married to my beloved wife for 10.2 10.2 years. She is my biggest support and the heart of our home.

We love animals. We have the black panthera-like cat Json (this word always sounds like a name for me) and little sweetie girl Pixel (Pixie for short). Also, we love foxes so much. That's why my logo and background with fox face :fox:
