K-Nishant-18/Nishant_Portfolio ? reverse-engineered prompt

Build me a personal developer portfolio that feels immersive and polished, not like a basic static resume site. I want a strong landing section with a 3D or WebGL style hero, smooth scrolling, animated transitions, parallax style motion, and little touches like a custom cursor and optional ambient music. It should clearly show my bio, skills, featured projects, project detail views, links, and a resume preview or download.

Please keep it fast, responsive, and clean on mobile and desktop. I also want a working backend so the contact form actually sends messages securely, and if there is already support for storing simple data through a database, keep that wired up in a sensible way. Make it easy for me to swap in my own content, project links, email settings, and visuals without digging through everything.

Use the structure already in this repo, make sure the frontend and API run together locally, and leave it ready to deploy. Look up current docs online if you need to.
