The Short Version

I'm Adam Piasecki (c4rt0 online), an Associate Software Engineer at Red Hat working on Fedora CoreOS and RHEL CoreOS - secure, minimal, auto-updating operating systems designed for containerised workloads.

Based in Rosslare, Ireland. I hold a Higher Diploma in Computer Science from Waterford Institute of Technology and am currently pursuing RHCSA and CKA (Certified Kubernetes Administrator) certifications in my spare time.

The Longer Version

Before software, I worked in geoscience. I started as a land surveyor, then moved to APEX Geoservices where I became a full-time geophysicist. From there I joined Murphy Surveys, continuing as a geophysicist. The analytical thinking transferred, but I kept being drawn to the tools rather than the surveys - automating data processing, building utilities for the team. Eventually I went back to college, studied Computer Science at WIT, and landed an internship at Red Hat in 2022.

That internship turned into a full-time role. Now I work on the tooling and infrastructure that assembles CoreOS - the operating system that powers OpenShift and runs containers at scale across thousands of production clusters.

I work in a LEAN, iterative delivery model, and I've owned and run Fedora releases end-to-end multiple times - from build through testing to shipping.

Speaking

I co-presented a workshop at DevConf.CZ 2024 titled "Maintenance-free self-hosting: deploy your cool apps on FCOS" - an 80-minute hands-on session covering Fedora CoreOS provisioning with Ignition/Butane, running containers on startup, automatic updates, and rollbacks.

Still a Surveyor at Heart

In my spare time, I write programs that help land surveyors with daily tasks - automating data comparisons, validating records, and generating reports. Old career, new tools.

Why adamcoding.com

I believe structured, high-quality learning resources should be free. I built this site and tools like the DSA Tracker because I know what it's like to change careers and navigate the overwhelming landscape of "learn to code" content. This site is my contribution back - practical resources, honest writing, and tools that actually help.

Community

I'm an active Fedora Project contributor with 21 community badges, including attendance at Flock 2023 and participation in CoreOS Test Days. I contribute to coreos-assembler, fedora-coreos-config, and the project's documentation.
