Highlights

• Migrated a ~300 RPS platform from a hand-configured server to an Ansible-provisioned Docker Swarm cluster, then to GKE managed by Terraform, with no downtime at any cutover.
• Introduced GitOps with Argo CD across 20+ services and internal tools, cutting deployment from over three minutes to under one and reducing rollback to a single Git revert.
• Migrated infrastructure as code from Terraform to Crossplane, eliminating configuration drift through continuous reconciliation against Git.
• Moved deployments from Helm to Argo CD and then to the rendered manifests pattern, making every diff reviewable as plain YAML and freeing Argo CD from template rendering.
• Moved secrets management to the External Secrets Operator, bringing secrets into the same GitOps flow and keeping every reference auditable.
• Moved stateful services onto Kubernetes operators — Postgres, ClickHouse, Redis, and Elasticsearch — and brought Kafka in-house from a managed provider onto Strimzi.
• Replaced self-hosted Nginx static delivery, a recurring source of outages, with Google Cloud Storage behind a CDN.

Highlights

• Brought a 20+ host vSphere estate and around 100 virtual machines under Ansible, AWX and Terraform, replacing hand-built servers with reproducible provisioning.
• Standardized continuous delivery across the 15+ microservices of the main application, giving eight developers one path to production instead of per-service scripts.
• Built observability for the microservices on EFK, Prometheus and Grafana, bringing logs and metrics into one place and shortening failure detection and diagnosis.
• Moved web service assets to MinIO object storage, taking file state off the application servers.

Highlights

• Replaced manual builds with a Jenkins and Nexus pipeline and moved dependency management to Gradle, cutting build time from hours to minutes.
• Migrated the platform from two hand-configured bare-metal servers to Mail.ru Cloud, then running on plain OpenStack, with infrastructure provisioned from Heat and Ansible.
• Built a Kubernetes cluster on OpenStack that provisions itself end to end, and moved the supporting systems — Elasticsearch and Jenkins — onto it.
• Moved the Liferay portal from Tomcat to WildFly.

Highlights

• Integrated FreeIPA, Foreman, isc-dhcp, and Zabbix into a single provisioning and monitoring chain.
• Automated deployment of test environments for incident-response drills.

Highlights

• Delivered turnkey office infrastructure — structured cabling, servers, and monitoring.

Highlights

• Built a secure multiservice network linking the central office and remote branches, with OpenVPN access for remote staff.
• Modernized the LAN end to end — cabling design, equipment selection, specifications, and vendor coordination.

Highlights

• Led the creation of the republic's largest fault-tolerant network.

Highlights

• Built the office LAN from scratch — equipment, structured cabling, AD domain — and established a dedicated channel to the parent company.
• Automated hardware inventory with OCS Inventory.

Highlights

• Connected the Chelyabinsk office and the Tryokhgorny plant networks.
• Migrated Windows Server 2003 R2 to 2008 without interrupting services.

Highlights

• Moved the logistics office to a new site with no break in warehouse operations.

Highlights

• Relocated the office together with its telephony without interrupting the working day.

Highlights

• Prepared a new retail point for launch — cabling, workstations, and staff training.

Highlights

• Built a preconfigured Windows XP deployment image with drivers and software bundled in, cutting installation on a new machine from about 90 minutes to roughly 10.
