Long-form technical writing on the problems I’ve actually run into, not generic listicles.
As an employee, someone else absorbs the cost of a wrong technical call. As a co-founder, you do. That one shift changes almost every decision, and it took me a while to notice it was happening.
Most state management questions get answered with a library opinion before anyone asks where the state actually lives, how often it changes, and who reads it. Start there instead.

Dark mode support usually starts clean and falls apart within months as hardcoded colors sneak back in. The fix isn't more discipline, it's making the wrong thing mechanically hard to do.
Adding a command palette to my own portfolio site touched keyboard handling, focus management, and state architecture more than most small UI components do. Here's what's actually involved past an input with a list under it.
