      As a developer, your job isn't about how much code you write, it's about how effectively you solve problems. The best code is code you don't write & maintain -- because you're using off-the-shelf solutions, or because you're picking solutions that involve fewer subproblems.

      One example. Your boss says "we need to detect when someone is cooking in the kitchen" A bad dev would buy a camera, spend $10,000 on data collection, and spend weeks building a custom CNN-LSTM architecture using a low-level library where they manage their own training loop.

          A good dev would buy a few $5 temperature sensors, spend a couple hours on data collection, train a simple logistic regression with sklearn, and be done in an afternoon. This dev also ends up with a far more reliable and maintainable system, with far less privacy implications.

          (A *really* bad dev would also spend an extra 2 weeks trying out their idea about using GANs for data augmentation in their activity classification CNN-LSTM, needlessly burning several MWh in the process.)

          A business analyst would ask "Why?". Probably more than once.

          Not-invented- here attitude, or a compulsive desire to be a 10x, can trigger adventures into the weeds and forests.
