* Maintaining global observability infrastructure (11 datacenters, 15 availability zones) * Creating an observability framework for the internal Kubernetes platform (metrics/logs/traces) Success stories: * Observability platform in Kubernetes built (Prometheus/Thanos, Loki, Tempo, GitOps) * VM inventory synchronization between company registers built (Python/Rest API) * Log aggregation platform migrated from HTTP to HTTPS without downtime for 5000 clients

* Leading the OPS squad of 3 people in Europe as a part of “Follow the Sun” Model * Driving Infrastructure-related technical projects with the focus on Platform Team topology Success stories: * Ascend microservices migrated to Kubernetes+EKS in order to adopt DevSecOps best practices * Intelligence microservices migrated (ECS → Kubernetes) for better usability and scalability

1st year – Complete Infrastructure Redesign in order to move to the Platform approach 2nd year – Sustainable platform operations and scaling in order to move to the Squad Model Success stories: * Application workload redesign (EC2+Chef → Docker+EKS) which allowed to scale the backend architecture and gradually move to “Squad Model” and microservices * CI/CD system redesign (Jenkins v.2019) to enable dynamic scaling and declarative pipelines

* Sustainable operations on the high load: peak time scaling, 13 NoSQL database clusters, on-call and incident management * Tech Stack renovation: infra as code, containerization, CI/CD pipelines redesign, etc. Success stories: * Infrastructure Codebase established: Terraform, Ansible playbooks, Python scripts set * Monolithic API migrated from EC2 VMs to Docker to speed up the deployment time
