Golang for backend

hi coders! ,I am new to golang and backend as a whole, I found golang pretty easy to learn due to my previous knowledge in CPP and python, the syntax felt pretty much the same so I decided to GO with golang for backend. I have learnt a decent amount of golang with some basic dependency injection layered model architecture using which I have created a basic project with the help of mongodb.
Now I want to progress further and become more proficient in golang and mongodb but I have no clue what to do after this please help me with that . I didn't follow any such yt playlist or something, did my own research and followed it and iam standing here. Help me with further roadmap and stuff to become a good golang developer.
