R&R stands for Runbooks & Ruminations.
This is where I write about systems I build, systems I break, and the trade-offs hiding inside both.
Some posts are practical — things that might save you an hour or a weekend.
Others are detours — thoughts on tools, interviews, AI, markets, and the quieter parts of engineering work.
I don’t think in absolutes. Most things depend on context.
But writing forces clarity, and clarity is useful.
This is me thinking in public.
