01 / INTRODUCTION

About me.

Systems Engineer with extensive experience supporting enterprise infrastructure across hybrid Windows, Linux, cloud, and on-premises environments. My work includes server administration, virtualization, networking, application hosting, troubleshooting, and operational automation across more than 35 client environments.

I develop administrative automation, investigate complex service dependencies, and support business-critical systems. My current technical focus is Linux systems engineering, configuration management, and reliable infrastructure operations, backed by practical work with Fedora, Proxmox, Ansible, Podman, and Python.
