I'm not talking about Figma. I mean, designing the actual product while you are building it. It takes design skill and experience doing it but completely doable.

Why?

I believe web user interfaces have converged and are almost at a point where things are very similar across the majority of products. Menu on the top/left. Logo on the top left, and your user session on the top right.

Buttons, tables and layouts have also converged. 

This may be killing originality and creativity, but at the same time it makes your product easier to understand and use, if typical conventions are followed.

The MVP

I've been building a lot of products in the past couple of years, I used to spend days in Figma designing the perfect interface, only to later code it and finally add the backend. It would take months to ship a product only to realize nobody wanted it, or I was solving only a problem I was having.

These days I jump straight to code and to the browser. Modern CSS frameworks like tailwind make it very easy to craft an easy to use interface in minutes (👋 AI ). You can then ship a usable product in just days.

Put the product out there, validate it, see if people are interested, rinse repeat.

THEN and only then polish up or be original. But always keep in mind your user's feedback.
