wow this is great job! Congrats. Curious if you can share your tech stack for this? Did you use any headless commerce to speed up development?
I've used VueJS/NuxtJS/Tailwind for the frontend and a NodeJS/ExpressJS/Postgres backend. I've developed everything custom and didn't rely on a headless commerce solution.
Best way to learn imo is to just start with an idea and tackle one task at a time. Before you know it, you'll have a fully functional and impressive creation on your hands
