I built WhaleLook - a Solana crypto wallet tracker to work with API's more (feedback wanted)

The Why
I've been teaching myself web development and realized I was stuck in tutorial hell - watching courses but not building anything real. So I decided to build something that actually uses live data and solves a problem I was curious about: tracking crypto wallet activity.
What I Built
WhaleLook is a Solana crypto wallet tracking platform where you can monitor blockchain addresses and see transaction activity in real-time.
🔗 Live site: whalelook.com

Frontend:JavaScript, HTML/CSS
Backend: Node.js (still learning this properly)
Deployment: Netlify
APIs: Blockchain APIs for real-time data

What I Learned
The hard parts:

Working with asynchronous data and managing API calls
Making the UI responsive and actually usable
Deploying something that isn't just localhost
Realizing "it works on my machine" means nothing

The good parts:

Seeing real data flow through something I built
Learning by breaking things and fixing them

What I'm Looking For
I need honest feedback from people who actually know what they're doing:

Does it work for you? (I've tested it but probably missed bugs)
Is the UX confusing? (I designed it, so I'm biased)
What would you add/remove/change?
Is this even useful or am I solving a non-existent problem?

This is a learning project, so brutal honesty is welcome. I'm not trying to sell anything - just want to know if I'm heading in the right direction.
What's Next
I'm currently working on:

Adding more features based on feedback
Learning proper full-stack architecture (still figuring this out)

If you're also learning or have built similar projects, would love to hear about your experience or challenges you faced.
Thanks for checking it out! 🚀
