Ah, the classic frontend-backend integration disaster. Two devs start a project with optimism and clean boundaries, only to end up a month later frantically trying to connect systems that were never designed to talk to each other. It's like watching two people build halves of a bridge from opposite sides of a canyon without ever checking if they're using the same measurements. The result? Electrocution by API incompatibility. The real tragedy is that after seven years in the industry, I still see this happen on almost every project. Communication? Requirements? Shared architecture planning? Nah, we'll just wing it and debug for three weeks straight instead.
