Multistep Form with React, Typescript and TailwindCSS

What are you most proud of, and what would you do differently next time?

This is my first project using typescript, so i'm still in the learning phase, anyway, i'm proud of completing it on my own. I'll build an array with every plan and addon so i can map over them and only write one single input field, it'll be much easier from styling perspective.

What specific areas of your project would you like help with?

Returning to the select plan step, as of right now, i build it only to switch between monthly and yearly plan, so if anyone as a solution for it, let me know. Any feedback is welcome.
