Skills

What the work is. Not a list of libraries.

Interfaces

Pages, forms, and states that stay readable after the visual pass — empty, error, and the cases nobody demoed.

Services

APIs with contracts you can rely on, not a pile of special cases that only make sense if you wrote them.

Data

Models that match how the product actually works, including the awkward parts people hope they can paper over.

Environment

I work on macOS, Windows, and Linux. Clients have machines. If it only runs where I developed it, it isn’t finished.

I use whatever a codebase already runs on. Percentages would be theater. When it fits, I pick the boring reliable option, not the one that looks newest on a résumé.
