HOW I WORK · Philosophy
- 01Weekly demos > month-end big bang: Clients trust progress they can see, and direction can be corrected early.
- 02Engineering before design, but both are required: Bad engineering won't survive even with great UI; bad design won't sell even with great tech.
- 03Mature tools beat trendy ones: Ship first; only sweat tech selection where lock-in matters.
- 04Use AI, don't depend on it: AI 5x's my coding speed, but architecture decisions and reviews always go through a human.
