How I work
1) Clarify
We define the goal and the failure mode (what works, what doesn't, for whom).
2) Minimal change
I apply the smallest safe fix first, and verify each step before moving on.
3) Document
You get a short summary of what changed and how to validate it later.

Email is the fastest way to reach me. Include: (1) what you need, (2) what you tried, and (3) any error message/screenshots.
