Professional Summary

Infrastructure & DevOps Engineer with over 8 years of experience in
designing scalable networks, virtualized environments, and monitoring
systems. I specialize in creating autonomous, air-gapped infrastructure for
ML/LLM solutions (VLLM, NVIDIA H200), implementing cybersecurity
practices (ISO 27001), and automating routine processes using Python. Deep
understanding of hardware optimization (GPU, NUMA) allows me to achieve
maximum performance for high-load and mission-critical systems.

Professional Experience

NDA | Senior DevOps & Network Engineer

Kyiv, Office | Jan 2025 – Present
● AI & Automation: Designed and deployed an autonomous air-gapped
infrastructure for LLM (NVIDIA H200) for defense purposes with
complete isolation from external networks, ensuring data confidentiality.
● Infrastructure Optimization: Achieved maximum VLLM inference
performance through deep hardware virtualization optimizations,
including NUMA-binding and GPU passthrough in an ESXi environment.
● Observability & Automation: Deployed a monitoring system (Zabbix,
Grafana) with custom Python scripts for automatic incident remediation,
which reduced MTTR (mean time to recovery) by 30%.
● Security & Networking: Integrated ISO 27001 security controls (log
management, patching, secure deployments) and Zero Inbound Ports
architecture with VLAN segmentation for system invisibility from the
outside.
● Implemented an asynchronous fault tolerance layer based on RabbitMQ
to preserve data in critical conditions.
● Skills & Technologies
 ● Python for automating infrastructure tasks (IaC, system administration)

PORTCITY GROUP | Infrastructure & Virtualization Engineer

Lutsk, Office | Sep 2022 – Jan 2025
● Virtualization: Implemented and optimized virtual environments
(Proxmox, VMware), reducing hardware costs by 20% and increasing
service density.
● Networking: Implemented network segmentation (VLAN) and
configured scalable VPN solutions (OpenVPN, IPsec) for 50+ remote
employees, ensuring zero downtime.
● Access Management: Implemented access policies (RBAC, Active
Directory, Azure AD) and automated device management through ESET
MDM.
● Security Audit: Deployed the Wazuh SIEM system for full integrity
auditing (FIM) and automated vulnerability detection.
● Deployed and optimized corporate video surveillance systems (CCTV,
NVR/DVR).
