bhaumik-1910/Portfolio ? reverse-engineered prompt

Build me a modern personal portfolio website for a developer.

I want a clean, responsive site that looks good on desktop and mobile and feels polished. It should have a strong hero section with my name, short intro, and a clear call to action, plus sections for my projects, technical skills, experience, and contact details or a contact form. Each project should be shown nicely with a short description and links to live demos or GitHub if available.

Please make the design simple, professional, and performance friendly, with smooth scrolling and good spacing. If it makes sense, include a light and dark mode toggle. Use a modern layout and make sure everything works well across screen sizes.

If you need to, look up current docs online before finishing so the setup and styling are solid.
