Hemanthsai456/Hemanth-Sai-Portfolio ? reverse-engineered prompt

Build me a modern personal portfolio website for an AI and Data Science student that feels polished, responsive, and easy to browse on phone, tablet, and desktop.

I want a single page site with a strong hero section, an about me section, featured projects, skills, education or experience, and contact links to GitHub, LinkedIn, and LeetCode. The projects should highlight work in data engineering, machine learning, data analytics, and full stack development, with nice cards and clear links out to each project.

Please make it feel alive with smooth scrolling, section highlighting in the navigation, subtle reveal animations, a typing effect, and some ambient particle style background detail. Keep it accessible, with good contrast, visible focus states, and clean spacing.

Use plain HTML, CSS, and JavaScript, and make sure the page includes the basic SEO and social sharing details like a preview image, metadata, and sitemap support. If you need to check anything current, look up the latest docs online.
