15+ years building cloud infrastructure, CI/CD pipelines, and production systems on AWS and Kubernetes. I lead engineering teams and deliver secure, observable environments with GitOps and DevSecOps.
DevOps, cloud infrastructure, and platform engineering at scale.
Hello! I'm Kamil Lelonek, a DevOps Engineer and technical leader with IT experience since 2010. My background spans cloud infrastructure and architecture, platform engineering, backend development, and team leadership. I hold a Master of Engineering in Computer Science and Management from Wroclaw University of Science and Technology in Poland.
I build distributed platforms, real-time systems, and data pipelines on AWS and Kubernetes. My focus is cloud architecture, CI/CD automation, and infrastructure reliability. I use AIOps for predictive monitoring, DevSecOps for automated scanning and compliance, and platform engineering with GitOps and internal developer portals to speed up delivery.
I lead engineering teams through technical project management, architecture design, and delivery. I align business goals with infrastructure planning, deployment orchestration, and incident response. Clear communication, realistic milestones, and removing blockers help teams ship secure, scalable, automated systems.

"Kamil has comprehensive specialist knowledge that is available at all times. He combines high technical competence with good expertise and is able to conduct thorough research on new topics in a fast-paced environment."
"Kamil has an extraordinarily high degree of initiative, independence and commitment and is always prepared to take on responsibility. He approaches challenges pragmatically and is able to cope with the highest workload and deadline pressure at all times."
"Within weeks it was clear he was the kind of engineer you rarely get to manage. He doesn't do the minimum - he reads the full context, figures out what should be done, and does it. That's not just a strong Staff Engineer, that's the kind of engineer who makes the people around him better."
