Had you been a bad developer you would have failed at the smaller companies. People thrive in different environments, and it can be jarring to go from a small shop to a large shop. They're different animals. I've worked at places where I'm the either the only dev or one of just a few. It's fun and it's easy to impress, but also easy to develop bad practices. But as long as you're getting the work done and your boss is happy, you're doing a good job. Larger places will be more formal (code reviews, sprints, very large code bases, etc etc). It sounds like you're beating yourself up for struggling with a task others thought would be "medium" complexity. It could just be that it's medium complexity to someone who knows the ropes at that particular company. It can be awkward to adjust to having more eyes on your code, but if you survived in the smaller environment, then in time you can adjust to the larger one. However, if you really feel out of your element, you may just want to go back to the smaller shops.
