About
I'm Andrei Vasiloiu. This is my technical learning blog.
I write about systems I have built, problems I have debugged, and engineering decisions I needed to understand well enough to explain. The subjects currently include cloud infrastructure, platform engineering, software, and data systems.
The useful part is rarely the final command or configuration. I try to preserve why a decision made sense, which assumptions were wrong, what failed, and what I would need to know before doing the work again.
These posts reflect the work and evidence available when I wrote them. They are not definitive documentation, and I update them when my understanding changes.
