How to build my own portfolio tracker website

Hi everyone,

To be fully transparent, I’m by no means a full stack developer.

My aspiration is to build something analogous to what Ark Invest and Cathie Wood have created on their website. The site doesn’t have to be complex. The core necessity would be an ability to create an accurately weighted portfolio chart showing my performance. How would I do this? Could any of you guys build it (obviously not for free)?

Cheers.
