software engineer / builder
Ethan Glover
I build resilient software, clarify complex domains, and leave systems easier to change.
01 / operating principles
How I work
Hypothesis-first.
I write the failing test before the implementation. Red, green, refactor — every PR, every feature, every bug fix.
Grounded in SWEBOK.
Estimates and tradeoffs grounded in the SWEBOK software engineering body of knowledge.
Domain-Driven Design as the bridge.
I often promote Domain-Driven Design as the bridge between development and business understanding. The model is the conversation.
