Just redesigned my tournament app from scratch after realizing the old version felt outdated and flat.

Time to leave tutorials behind and code from scratch.
Over the next few weeks, I’ll be building multiple full frontend projects, from design to deploy.
Once the portfolio is solid, it’s time for the next phase:
→ React
→ AI-integrated apps

Let’s go 🚀

• DOM logic
• Clipboard copy
• Buttons & structureInsight from The Design of Everyday Things:
👉 Good design doesn’t assume user understanding — it guides.UX is about clarity.#JavaScript #UXDesign #FrontendDev #BuildInPublic #100DaysOfCode

UX thought of the day:
We don’t design for screens — we design for *people*.

If we don’t understand how people think, our designs will confuse, mislead or frustrate.

@samm_duc Thank you! You're absolutely right, testing is where the real learning begins.
Do you have any tips or tools for lightweight user testing you’d recommend at an early stage?
