<strong>Every repo here is a delivery narrative, not a demo.</strong>
|
|
Architecture decisions, governance patterns, baseline-to-model flows,

and the boundaries where manual work stops and automation starts.

Built for hiring managers who want to read code — and for engineers
|
|
who want to understand why the code was written.
