Dmitry Bogoliubov
Senior Systems & Infrastructure Engineer Infrastructure Resilience & Defensive Operations
I specialize in architecting and managing high-availability IT ecosystems where system reliability is an inherent architectural property rather than a byproduct of routine maintenance. With over 15 years of cross-border experience in the U.S. and Israel, I help enterprises build self-healing, scalable infrastructures that eliminate technical debt. My methodology was forged in elite high-pressure environments where the cost of failure was critical, enabling me to ensure business continuity across the most demanding digital landscapes.
Cloud Architecture & FinOps Strategy
My focus is on engineering seamless hybrid environments, integrating on-premises assets with major cloud providers (AWS, Azure).
Business Continuity: I orchestrate secure multi-region deployments (EC2, VPC) with automated failover mechanisms, ensuring operational integrity even during regional outages.
Cloud Financial Management (FinOps): I institutionalize fiscal accountability through rightsizing and strategic optimization of Reserved and Spot instances, delivering a sustainable 15% reduction in cloud expenditure while maintaining peak performance.
Mission-Critical ERP Support: Extensive experience sustaining 99.9% uptime for enterprise-grade ERP clusters (SAP, Spruce, Priority), supporting core financial and operational nodes.
Defensive Operations: Infrastructure Security
I treat security as a fundamental pillar of infrastructure design, championing a “Zero-Drift” posture to eliminate unauthorized configuration changes.
Endpoint & Cloud Security: I manage comprehensive protection for 500+ endpoints, leveraging advanced stacks including CrowdStrike Falcon, SentinelOne, and Armor Anywhere.
Proactive Remediation: By leveraging automated patch orchestration and EPSS-based vulnerability prioritization, I shrink the exploit window and mitigate 40% of critical threat vectors before they can be weaponized.
Perimeter Defense: I architect tiered network security utilizing Sophos, FortiGate, and Check Point, complemented by resilient site-to-site VPN tunneling.
Strategic Leadership & System Modernization
I transform IT departments from “reactive cost centers” into strategic assets through deep automation of the system lifecycle. I bridge the gap between Development and Operations (DevOps), fostering a culture of shared ownership and providing high-level technical mentorship to engineering teams.
Scalability via IaC: By institutionalizing Infrastructure as Code (IaC) using Octopus Deploy and GitHub, I eliminate human error from the deployment pipeline, reclaiming 25% of engineering bandwidth for innovation.
Lifecycle Modernization: I oversee large-scale migrations from legacy hardware to high-performance hyperconverged platforms (Nutanix, VMware), yielding a 35% increase in transaction throughput in past engagements.
Quantifiable Business Impact:
Risk Mitigation: 40% reduction in operational risk via automated governance and configuration enforcement.
Performance Optimization: 35% gain in core system performance through virtualization-driven modernization.
Fiscal Impact: Realized 20% savings in telecom overhead and 15% in cloud expenditure through architectural re-engineering and cost-monitoring frameworks.
My methodology—honed in Quick Response Teams (QRT) and refined within the corporate enterprise—is dedicated to delivering an “invisible” infrastructure: a robust, fiscally transparent, and secure foundation that allows the business to focus on product innovation rather than firefighting.
