02 / THE ENGINEER

From the data centre
to the cloud.

My background spans physical infrastructure, global networks and cloud automation. I understand how the layers fit together.

I've worked with enterprise teams and cybersecurity startups, building tools that make infrastructure easier to operate. My experience includes Cellebrite, Google, Groupon, Dell, xorlab and London Stock Exchange Group, with contract roles across several of those organisations.

My experience includes CI/CD migration and exploration of AI-assisted diagnosis and repair of pipelines and code at Cellebrite, deployment of ML services on Kubernetes, and GenAI / LLM workloads in a private Proxmox lab.

Based in Poland, with years of experience working remotely across international teams. I bring hands-on engineering, clear communication and ownership of the work.
