Devops

Complete automation of a Proxmox environment & VM lifecycle optimization: Automated Proxmox node configuration using Ansible (SSH, certificates, encryption), reducing manual setup from 2–3 hours per node to under 15 minutes and eliminating repetitive errors. Implemented fully automated provisioning of Linux VMs (Cloud-Init) and Windows VMs (WinRM), reducing OS installation time from 40 minutes to 5–7 minutes per VM. Integrated network and identity configuration (static IPs, DHCP, DNS, Active Directory), enabling production-ready VMs on first boot and reducing onboarding incidents by 70%. Developed a Python-based graphical interface (CustomTkinter) to simplify VM creation and management for internal teams, reducing support requests by 40% and ensuring standardized provisioning. Deployed comprehensive monitoring with Zabbix (CPU, RAM, disk, services), enabling real-time monitoring and reducing unexpected downtime by 25%. Implemented a mass VM cloning mechanism using hardened templates, enabling the deployment of 20–30 VMs within minutes instead of several days previously.
