Despite what others may say @mtf is correct, This requires a high degree of problem-solving skills. This also requires a very high ability to translate your plans into code.
This is very true, Websites who have a team of developers that are much simpler take years to make
There’s a lot of problems, Here is one to figure out that has no relation to code: How will you store 360 photos. 5 minutes of 360 video at a trash bitrate of 20mbps is 0.7 gigabytes. Most Instagram videos are as low as 20-100megabytes. Figuring out a way to compress/store/deliver the content of said size in an efficient manner would be very hard.
What you could do that would have a greater chance of success is to build an API that someone like Facebook or Snapchat would want to buy. There are a lot of problems with the current technology. Although this would require Electrical Engineers and other industry professionals.
