Hi there,
I hope you are doing well. I recently discovered your Open Source project (Profile Rank / FitFinder), and I’m genuinely impressed with the idea and UI/UX approach.

I’m a frontend web developer skilled in HTML, CSS, JavaScript, Bootstrap, Tailwind CSS, GSAP, and React.js. I’m very interested in contributing to this project and learning through real development.

Can you please assign me a beginner-friendly issue or task so I can start contributing? I’m highly motivated and available to work immediately.

Looking forward to your positive response. Thank you!
