skills/ · three domains, one stack

Three domains. One stack.

Skills grouped the way a hiring manager reads them: what I build, how I validate it, and what I ship it with. Each skill is paired with a self-rated proficiency ladder (1 = exposure ·5 = production) and the number of years I've practiced it.

Self-rated, not self-inflated. Proficiency dots are my honest answer to "could I ship this to production on Monday without help?" Tradeoffs between languages, libraries, and domains are explicit: e.g., I can ship production Python but my Docker is working, not expert. Years of practice reflect actual use, not calendar time since first exposure.

stack = build \cdot validate \cdot ship where validate = G1 .. G31
