Name tokens by role, not by value — and why that one rule saves weeks.
The short version
Most problems here are not technical. They come from decisions made without a clear constraint. Write the constraint down first, then pick the tool.
We measure before and after every change, keep the diff small, and ship behind a flag when the blast radius is unclear.
Measure first. Opinions are cheap; traces are not.
What we do on client projects
Every engagement starts with an audit and a one-page plan. The plan lists the three changes with the highest return, an owner for each and how we will know it worked.
