About

I am a senior-level IT leader and systems engineer with over 8 years of experience driving infrastructure modernization, systems automation, and secure IT architecture across enterprise, banking, and public-sector environments. With a hybrid background in both technical execution and strategic management, I’ve successfully led company-wide IT transformations, managed server fleets (Windows Server, Linux/Ubuntu), deployed enterprise virtualization platforms (VMware vSphere, Proxmox), and implemented automation solutions using Docker, Ansible, and GitLab CI/CD. I have extensive experience in network engineering (MikroTik, Cisco, Kerio), Active Directory/GPO design, and endpoint security management (Kaspersky Security Center, HoneyPot, EDS). Beyond traditional infrastructure, I bring deep expertise in low-level engineering and binary analysis. I write and debug x86 Assembly (NASM), understand PE file structure, and have hands-on reverse engineering experience — including completing 4 out of 5 technical tasks for a malware analysis role at Kaspersky Lab. This gives me an uncommon edge in security-focused roles, Red Team support, and system internals. As a former IT Manager and interim CTO, I’ve been responsible for team leadership, budgeting, procurement, and cross-departmental IT alignment — all while remaining hands-on and technically self-sufficient. I don’t outsource complexity — I own it, solve it, and document it. I engineer reliable, secure, and scalable systems — and I understand them all the way down to the opcode. I maintain a technical GitHub profile (https://github.com/HopelessCompass) with 200+ active followers — a number that continues to grow as I share reverse engineering, automation, and low-level programming content. This reflects the trust and engagement of the developer and security community in my work. I am currently based in Moscow and actively seeking relocation opportunities in Serbia, with particular interest in infrastructure leadership, security engineering, DevOps, or reverse engineering positions in innovative companies or international teams.
