I read that one of the disadvantages of DEXs is complicated UI/UX, this makes newbies and basic users run away from it or end up being scammed. If you can replicate what CEXs have in their front end, it will be a win for amateur users.
This is (for now at least) a solo project. I have been trading crypto for almost a decade, but my tech skills are pretty basic. However, I think that can end up being a good thing, because the problem with having a tech wizard make a DEX is they tend to assume everyone else is a wizard too, and so the UX ends up being way too complicated.
I have never experienced this, but it seems that a statement of yours is valid. When a team is made up of all techy people, they'll end up designing the UX like takes, but a basic programmer could understand and implement the basics things that would be missing.
