At Group-IB, I designed and built an internal managed HA PostgreSQL service using the Autobase Ansible collection. After migrating selected cloud-managed workloads, I reduced billed PostgreSQL service and network costs by approximately 84% while retaining comparable service capabilities.
I also implemented MAAS/LXD-based bare-metal management across OVH and Hetzner, provisioned Kubernetes with Kubespray, and delivered applications with Argo CD across company infrastructure and isolated customer on-premises environments.
At Group-IB, I developed LLM-assisted vulnerability triage for an internal portal, using self-hosted models and the company knowledge base to score findings and prioritize investigation and remediation. I also handle production incidents, coordinate mitigation, and prepare postmortems as part of SRE on-call rotations.
Previously, at Hystax, I introduced Infrastructure as Code practices and moved SaaS product components and infrastructure services to a highly available Kubernetes platform. At Directum, I supported customer-facing SaaS services and improved visibility into infrastructure and application health.
