Ask HN: I want to make an electric skateboard for heavy shopping. How to start?

Hey HN. I got rid of my car almost 10 years ago, and I live 15 minutes from Walmart. I sometimes have to go and get a crate of beer, milk, some coke-zero and this is a major pain in the ass to trek home. Tears my hands to ribbons. For years I have wanted a box on wheels that I can control. I am a software guy. Think of a radio controlled car, but a bit more meat. I know there are weird boards that look almost like lego with holes, and things like Raspberry PIs or Arduinos. Would anyone be able to point me to a single starting point for my electronic journey towards this goal so I can spend 2022 with a new hobby? Thanks for reading.
