Deeply comfortable in the demanding application engineering space.
Very familiar with C# and dotnet.
Comfortable taking existing decisions, applying taste and judgment, and engineering modern solutions.

Ability to distinguish between good AI-generated output and plausible-sounding output.

Own outcomes and have agency; find ways to achieve goals without waiting for perfect conditions or blaming circumstances.

Build things other engineers want to adopt by listening to them, treating their friction as your defect, and caring about developer experience as much as technical correctness.
Believe in writing as a forcing function for thinking and clarity; love writing.
