smritisingh110/portfolio_smriti ? reverse-engineered prompt

Build me a simple personal portfolio website for Smriti Singh Bhadauriya, a Java developer. I want it to be a clean one page site that looks good on desktop and mobile, with a strong intro section, about me, skills, experience, projects, resume, and contact details. It should be easy to open locally by just opening the index file in a browser, and I want the layout and styling to feel polished but still simple.

Please make sure the page has placeholders I can easily replace for my email, LinkedIn, GitHub, and resume link. Add a resume button that points to a local resume PDF file. Keep the content professional and suitable for a developer portfolio, and make it easy for me to edit the wording later if needed. If anything needs current best practice help, look it up online first.
