Freelance Infrastructure & Automation Engineer
Self Employed • Freiberufler
Sep 2022 - Jun 2026 • 3 yrs 9 mos
I design, deploy, and automate robust open-source IT infrastructure and containerized environments. My focus is on creating secure, highly available systems using Infrastructure as Code (IaC) and modern networking protocols. Key deployments include: Enterprise SD-WAN Automation: Engineered a fault-tolerant Hub-and-Spoke network topology. Utilized Ansible to completely automate the configuration of VyOS routers, deploying secure kernel-space WireGuard tunnels and integrating eBGP for dynamic, automated routing. Secure Private Cloud Architecture: Architected a multi-tier Nextcloud environment using Docker microservices. Implemented strict network isolation, automated SSL/TLS management via Caddy, and optimized performance using Redis for distributed caching and transactional file locking alongside PostgreSQL. Containerized Web Server Provisioning: Developed an automated infrastructure solution using Docker Compose to instantly provision fully functional LEMP stacks (Nginx, MySQL, PHP), streamlining web application hosting and database management.
