Hi, I'm Valtteri.

Cloud, HPC, and Platform Architect.

Here I write about cloud architecture, high-performance computing, systems thinking, compliance, and the infrastructure that powers modern software. I also share stories and thoughts about my life outside of tech, including sailing, traveling, and my other adventures.
