Ask HN: What knowledge or skills I should learn working in healthcare as SDE?

Hi Everyone, I have just recently joined a healthcare company and there are a lot of new terminologies that I don't understand ( coming from an e-commerce background). I joined this company because I want to build my career in healthcare or even start a startup after some time. I think healthcare with AI will be the future. Following this vision, I want to learn about the industry from the inside. But there is a lot to learn. Any ideas on how should with the foundation then move to more complex terminologies in the healthcare industry.
