Engineering teams. Running platforms.

A decade in platform engineering and infrastructure automation. I've spent years as the bridge between technical reality and leadership, and now I'm on the other side of it, building teams that are skilled, motivated, and effective. I haven't left the technical side behind. I just have better reasons to stay close to it.
