I am a self taught programmer and ML engineer. At work I find myself usually downloading models from huggingaface and sometimes training them to get the job done. That is enough to impress people in my country. But I know I'm not a good ML engineer. I want to get good, real good, Andrej Karpathy good dare I say, How do I do it? I have done the Andrew Ng course and the Fast.ai course. Those got me into the field, but what do I do to thrive in this field. I really want to do some great work and help people. Great people from HN please tell me how can I level up as an ML engineer.
