Sounds to me like this is primarily a self-esteem issue. What helped me in the past is looking at code written by others, figuring out how they solved complex problems. Follow their implementations end to end, try to apply their thinking to your area. The bad thing is that there are no shortcuts to becoming a confident engineer. The good thing is that everyone has to go through this process. So don’t feel intimidated, just focus on practice, find tech that really engages you vs tech that someone else thinks is good/complex.
