Build me a clean personal portfolio website for a data analyst named Uzair Mukhtar.

I want it to feel polished and modern, but still lightweight and fast, with a responsive layout that looks good on phone, tablet, and desktop. Include sections for experience, projects, certifications, skills, and contact details, plus a simple way to show the resume or CV info. Make sure the site has a light and dark theme that remembers the user’s choice, and keep the navigation easy to use with good keyboard focus and accessible structure.

Please also set it up so it works well for search and sharing, with the right page metadata, structured data, sitemap, and robots file. It should be a static site with no extra build step, just HTML, CSS, and a little JavaScript. If you need to check anything current, look up the latest docs online first.
