I recommend this underrated substack: https://uxmovement.substack.com

I've learned a lot from there about forms and table design.

I find this book really helpful: https://www.refactoringui.com/

Along with reading Nielsen Norman articles on best practices and such.

For UI and widgets, I personally like MUI and find it better the Shadcn, but whatever, just start with something usable and polished enough, even if it's not the prettiest, and improve it later when you can hire a designer.

You might also be able to find some relative cheap freelance design just to get a basic look and feel and maybe a logo.

For product design methods and collaborative exercises: https://www.aha.io You can use component libraries like skeleton UI:https://www.skeleton.dev/ or Schadcn: https://ui.shadcn.com/, so you don't have to design the components an style guides yourself. If you are interested in reading just one book and be confident about your design decisions, read : The User Experience Team of One by Leah Buley.

Below are the websites that i usually used for ideas, resources and guidance for critical UX considerations. https://www.ux-checklist.com/ https://uxplanet.org/ https://uigoodies.com/

Mobbin and dribbble have some great UI/UX to draw inspiration from.

Monitoring and finding solutions on https://ux.stackexchange.com/ really helped us.

[There is no detail to the question. This answer is generic]

Working is the most important UX element and if it works it is good enough to ship.

If it doesn’t work, then other aspects of the UX are irrelevant…there are no users to use what doesn’t work and if you can’t make it work UX resources aren’t going to help anything other than help you avoid the big problem.

Should you learn some design? Of course, but the only way to learn design is by designing…it’s like singing and keepee-uppee, no book can show you how to carry a tune or get you to ten juggles.

So to reiterate, ship.

Good luck.
