Product List with Cart as MERN stack app

What are you most proud of, and what would you do differently next time?

Most proud of building out a Frontend Mentor challenge to a full stack MERN app.

Next time I will think better in advance on how to render images.

What challenges did you encounter, and how did you overcome them?

Most challenges were with rendering images correctly during development in localhost, but even more in production on Github Pages. I solved these in the end but refrained from publishing the full stack on Render.

What specific areas of your project would you like help with?

Open to ideas, tips and comments in general, but if anyone knows a good way to publish both backend and frontend, let me know.
