For earning BTC, I've found @DarthCoin's guide and a blog most useful till now. However, since I'm also a beginner with zero experience in Bitcoin's backend architecture, it's little hard for me to land a job. I'm trying to learn about LN nodes and BTC backend etc. at my own pace. [FOR HIRE] I am proficient with python, R and other data science libraries. I can also design UI/UX experiments like AB testing, questionnaires like this. You can explore these links too.
