Computational Linguist here, currently getting a PhD in NLP. If you want to get into that area, full-stack development isn't going to help (although it's a cool thing to do on its own if you're interested). Web development and Data Science (ML /DL etc.) are very different thigns. Also, while SQL is helpful in a lot of ML projects, natural language data is unstructured and is not to be stored in SQL databases. Instead, I'd suggest learning the fundamentals of Machine Learning first. Once you're there, you can start specializing in NLp topics. As a lawyer, your strength will probably be understanding the methods enough so you can assess whether or not a certain problem can be solved with NLP. Hope this helps!
