Congrats and kudos on the nice website (how long did the website take?). Also, did you use golang for the product?
Actually, for the website I relied heavily on antd ( https://github.com/ant-design/ant-design/ ) for the design. I cannot really say how long it took because it's always been developed alongise the backend.
Aaaand yes, I LOVE golang, even more after creating Notify17 using it. The clarity of that language is impressive.
