It sounds like your area is specifically on a service and web front end. Can you describe what you’re wanting to do, even at a very high level?
Node, React, etc. this might all just be overkill.
If I had to do something on the web, I'd use the LAMP stack at my ISP.
I'd avoid SPAs as hell. Just a total waste of my time/money and end user's resources. If employer wants to use his money for SPAs, I'd build them happily.
