How I think about production systems.
A small set of positions that have held up under real operational weight. They're not rules — they're what the work has taught me.
On legacy systems.
Refactors should preserve every grain of business logic accumulated over years of real-world use. Speed is cheap. Correctness is expensive.
On measurement.
A system isn't faster because the code is cleaner. It's faster because a specific query, on a specific table, under a specific load, returns in less time.
On automation.
The goal isn't to remove humans from the loop. It's to remove the tasks that were never worth their time in the first place.
On production readiness.
Production-ready means the system behaves predictably on the days no one is watching.
On legacy code.
Legacy isn't a code problem. It's an accumulated-context problem.
On reliability.
Reliability isn't uptime. It's the quiet confidence that operations teams stop thinking about the system because it stopped surprising them.
A curated set of systems shipped into production.
