Looks to be something like a 3-tier app plus cache... nice. And the chosen tech stack are industry mainstays, so your time will not be wasted. I see some good points already commented, I will try not to be too repetitive. Keep things as simple and lean as possible to begin with, then add complexity when needed. Not before. Claude and other LLMs are great for content generation and are to be embraced but not trusted. Don't let Claude or any of its siblings run you around in circles. Finally, this one really helped me; don't limit your learning materials to current generation social media and bite sized treatments. I'm not suggesting to do all the following, but there is gold in there... Old school texts still have a lot going for them, public domain university lectures and problem sets are a world of fun too. Don't be afraid to study codebases you respect in depth. Build, debug, extend etc. I have had hours of fun with postgres and mysql in particular.
