Never start drawing architecture boxes immediately. Begin by asking clarifying questions to establish both business and technical constraints. Never jump straight into choosing an ML model

Never jump straight into choosing an ML model. Spend the first 5 to 10 minutes clarifying the goals, constraints, and business requirements.

: Focus on both visual and text-based search systems.
