If you've ever seen the TV show Silicon Valley, "Big Head" played this archetype very well. There are always a few people in every company who do so. Consider yourself lucky in some ways; you probably haven't rocked anyone's boat, which might catapult you to management and beyond!

If you don't go to management, it's probably worth doing another 5 hours of Leetcode each week. Regardless of how much work you do, the career lifespan at most companies is less than ten years. So you will have to prove you are a coder 4-5 times in your life, and probably at least once when you are over 50.
