Hello, I'm Jarek.
$/~ DevOps & Platform Engineer_
Bridging the gap between reliable infrastructure and modern DevOps. With over 6 years of experience and a deep background in Linux systems, I architect scalable, automated platforms using containerization and Infrastructure as Code. Currently contributing to Basecamp's Omarchy Linux distribution, personally invited by David Heinemeier Hansson.
About Me
I am a DevOps & Infrastructure Engineer from the Czech Republic, dedicated to modernizing operations through automation and solid engineering principles. My foundation is built on deep Linux and networking knowledge, which I now leverage to design robust, cloud-native environments and container orchestration platforms.
I treat infrastructure as software, utilizing Python and modern tooling to build custom automation and internal developer platforms. Whether it's crafting CI/CD pipelines or developing monitoring solutions, I aim for efficiency and observability. As a daily user and contributor to Omarchy Linux, I maintain a strong connection to the system internals that power modern tech stacks.
My approach combines the reliability of seasoned systems administration with the agility of modern DevOps. I don't just maintain servers; I engineer resilient platforms. My goal is to abstract complexity and provide stable, scalable foundations that allow applications and developers to thrive.

Projects
The Portfolio Meta-Project
What better showcases my infrastructure skills than the very platform presenting them? This entire website, from infrastructure to deployment, is my project. It runs on my self-hosted server using Proxmox virtualization, which I personally manage, and demonstrates the practical use of technologies like Python, Django, Docker, and CI/CD to build a complete, production-grade solution. The server infrastructure, monitoring, backups, and deployment pipeline are all designed and maintained by me.
Technologies: Django, PostgreSQL, Docker, CI/CD, Proxmox, Traefik, Self-hosting
Omarchy Linux Distribution - Open Source Contributor
Active contributor to Basecamp's enterprise-grade Arch-based Linux distribution. Personally invited by David Heinemeier Hansson to join the development team. Developed critical system components including the main DNS configuration script and boot process improvements. 10+ merged pull requests in a project used by thousands of developers worldwide.
Technologies: Bash, Linux, systemd, Git, DNS configuration
DevTracker - Infrastructure Automation & Project Management
A comprehensive Django-based system for infrastructure automation and project management with time tracking, task management, and progress monitoring. Features user authentication, project ownership, and a powerful admin interface. Built with infrastructure reliability in mind—comprehensive testing (95% coverage), Docker containerization, and automated deployment pipeline.
Technologies: Django, PostgreSQL, pytest, Docker, GitHub Actions
Lantern - Network Interface Manager
A lightweight TUI (Terminal User Interface) for managing network interfaces on Linux, built in Rust. Supports WiFi, VPN, and IPv4/IPv6 configurations through systemd-networkd. This systems-level project showcases my ability to work across the entire technology stack—from low-level networking and systems programming to high-level infrastructure automation.
Technologies: Rust, Ratatui, systemd-networkd, Linux networking
