How do you balance between over-engineering and following design principles?

I prioritize YAGNI (You Aren’t Gonna Need It) to avoid over-engineering. SOLID principles

guide design for flexibility and maintainability, but I apply them pragmatically: start with

simple solutions and refactor as requirements evolve. Writing tests early helps identify pain

points justifying additional abstractions. Communication with the team ensures we don’t add

complexity prematurely but keep the codebase adaptable.
