Krisztian Banhidy

Senior Lead DevOps Engineer at Peak

Who I Am

Cloud infrastructure leader with 17+ years of hands-on experience — from managing HP-UX servers in a locomotive company to leading cloud strategy at one of Turkey's top gaming companies. I've built CDNs at IBM, automated AWS at LogMeIn, designed cloud platforms at T-Systems, and founded my own consultancy. Currently leading the cloud team at Peak, where I drive infrastructure architecture, FinOps cost optimization, security operations, and vendor management across a large-scale gaming platform.

I'm a FinOps Foundation contributor with 7 published articles on cloud cost optimization, a Kubernetes-certified engineer (CKA + CKAD), and an active open-source builder. When I'm not in the cloud, I'm underwater — I build decompression algorithm software for the technical diving community. I believe the best infrastructure is invisible: reliable, cost-efficient, and boring in the best possible way.
