Things to follow when switched from QA to Dev.

I have 10 years of experience in IT. Currently working as test automation engineer. I am going through a transition into Java development - spring boot. The main reasons for switching is better work challenges in Dev than QA and also better salary. Also I have plans to start/explore something on my own in future.

Please suggest me and guide to get better at software development. I want to know what websites, threads to follow. What are better routines of Software developer and how do they approach. I feel I am starting from level 1 with development.
