- Containerized and migrated a system of over 100 microservices from EC2 and Nomad-based environments to EKS, significantly reducing deployment time tenfold, increasing availability, and saving almost 50% on monthly compute costs.
- Implemented a disaster recovery plan for applications on Kubernetes and the underlying infrastructure, reducing the recovery time from hours to minutes and ensuring minimal downtime.
- Replaced Datadog subscription with a self-hosted monitoring system based on VictoriaMetrics and Grafana, saving over half a million dollars annually (30x cost reduction).
- Migrated microservices from Docker Swarm to AKS, dramatically reducing manual workload for engineering teams, minimizing the need for engineers’ intervention during incidents, and improving application availability.
- Led the implementation of an internal developer platform, promoting a principle of end-to-end ownership of applications by their developers, eliminating knowledge silos and resulting in improved visibility and faster incident response times.
- Brought data science team’s delivery processes from entirely manual to wholly automated in all stages, from data preparation and model training to deployment and monitoring, following MLOps best practices, dramatically improving the team’s efficiency and satisfaction.
- Replaced legacy internal VPN system with a modern zero-trust solution, implementing least privilege principles, strongly enhancing security, and minimizing risks.
- Led the design, implementation, and maintenance of Kubernetes clusters for multiple projects, ensuring high availability, scalability, and security of microservices, enabling fast and zero-downtime migration from Docker Swarm, Nomad, and EC2 environments.
- Worked with development teams to create various CI/CD pipelines using tools like GitHub Actions, GitLab CI, ArgoCD, and Spinnaker, automating the complete delivery cycle.
- Built and managed infrastructure as code using Terraform, enabling repeatable and consistent automated deployments.
- Designed and developed observability solutions using VictoriaMetrics, Prometheus, Grafana, and Elasticsearch (ELK).
- Implemented and maintained various security practices, including access control, network policies, automated code and artifact scanning, and auditing.
- Improved developer experience by introducing a self-service platform using Backstage, providing engineering teams with a one-stop tool for creating, monitoring, and troubleshooting their services.
- Coded internal tools and services in Python and Golang, such as CLI, CI/CD tools, Kubernetes operators, and Prometheus exporters.
- Mentored and trained developers on Kubernetes and Terraform best practices and DevOps methodologies.
I seek opportunities in a Kubernetes-centric cloud environment that leverages modern industry-standard practices, such as Infrastructure-as-Code and GitOps, and employs up-to-date tooling. I avoid working with legacy software, on-premise infrastructure, and tools like Jenkins and Windows.

In addition, I value efficient time management and prefer to minimize the amount of time spent in meetings.

I am prioritizing collaboration with companies aligning with my values and principles. As such, I refrain from engaging with organizations with a track record of conducting mass layoffs or those that have ceased hiring initiatives in Ukraine.
