Could it be that their standards of quality aren't up to yours? If they're slapping shit together, hoping it works, and you're actually doing it right... you will always be slower.

Look at Advent of Code, for example. I'll never, ever, finish in the top 100, if you watch the videos of people who compete at that level, you see they start writing code before they've even had time to read the entire problem.

Quality takes time. Some of us have a higher standard, below which we will not go, which makes us slower in the short run. It also makes us faster in the long run.
