Hi there πŸ‘‹ I'm Oleh πŸ‘¨β€πŸ’»

DevOps / SRE engineer with strong focus on infrastructure design and reliability.

I work closely with development teams, design scalable systems, and build infrastructure that is resilient, cost-efficient, and production-ready.

Experience:

Strong hands-on experience with:

  • Infrastructure as Code (Terraform)
  • Configuration Management (Ansible)
  • CI/CD (GitLab CI)
  • Public & private clouds (AWS, OpenStack)
  • Containers & orchestration (Docker, Kubernetes - self-managed)
  • Monitoring & observability (Prometheus, Grafana)
  • Logging (Graylog, Filebeat)
  • Networking & security (network isolation, firewalling, segmentation)

Strong networking background (ex-Network Engineer), applied to cloud-native and distributed systems.

Design and operation of production infrastructure across multiple datacenters with focus on reliability, scalability and cost-efficiency.

Close collaboration with development teams across all SDLC stages.

Abilities:

  • Design and build resilient infrastructure architectures
  • Implement and optimize CI/CD pipelines
  • Build and operate Kubernetes clusters (self-managed)
  • Improve system performance and scalability
  • Ensure proper network isolation and infrastructure security
  • Apply networking principles to distributed systems design
  • Automate infrastructure provisioning and configuration

Key achievements:

  • Migrated infrastructure to self-managed Kubernetes cluster
    β†’ Reduced infrastructure costs significantly (~3x)
    β†’ Improved system performance and scalability

  • Improved system responsiveness and reduced latency under load

  • Designed multi-datacenter infrastructure for higher availability and fault tolerance

  • Optimized CI/CD processes for faster and more reliable deployments
