I’m Alexandr — a Senior Engineer at CrowdStrike working on backend systems and cloud infrastructure, mostly in Go.

After 13+ years building things at scale, I’ve reached a point where I feel like I have something worth writing down. Not theory — just what I’ve learned from actually doing it.

The name is deliberate. “The Append-Only Log” is an homage to the kind of problems I find most interesting: distributed systems, high-scale infrastructure, the engineering challenges where correctness and scale are both non-negotiable.

This blog was built AI-assisted — the layout, the components, the styling, all shaped through conversation with an AI tool. That makes it a small working example of how I think about AI in general: it’s a capable tool, and in good hands it does good work. It’s not a silver bullet, it’s not going to reshape the industry — it’s just another tool to get better at.

Expect posts about distributed systems and backend engineering, and occasional takes on AI-assisted development from a practical angle, not an evangelical one.

Thanks for stopping by.
