Linux System Engineer who automated VMware provisioning with Ansible, cutting setup time to about 5 minutes.

At SPUTNIX, I built an Ansible workflow with playbooks and reusable roles for VMware provisioning after Terraform could not be used. It automated VM setup, hardening, network configuration, and service installation, reducing provisioning time from 30–60 minutes to about 5 minutes.

I also developed a Python utility for OpenVPN configuration generation with LDAP integration, and maintained Zabbix while deploying Prometheus and Grafana. Earlier, I built a Python ticket management solution using the Telegram API and automated workstation deployment with Bash.
