About Me

Mariusz Derela

I design and build distributed data and AI infrastructures: systems that turn high-volume telemetry and event streams into something teams can understand and act on. My focus lies in real-time data processing, AI observability, and secure architectures that bridge on-prem and cloud environments.

As a Principal DevSecOps Architect, I design and implement Security Data Lakes powered by AI and machine learning to detect threats, correlate signals, and enable proactive defense across large, distributed ecosystems.

I’ve spent nearly 15 years working with leading financial institutions, building and securing critical data and analytics platforms under strict compliance and performance requirements. This experience shaped how I design systems: scalable, resilient, and compliant by design.

My journey started in the world of Linux, open-source, and security engineering. In 2004 I co-founded the Jaworzno Linux Users Group (JLUG) and those roots still guide how I think about systems today. Simplicity, transparency, and automation first.

Privately, husband of Klaudia and father of Mia. They remind me every day that the most important systems are the ones that work at home.
