Responsive Portfolio Site Creation

I’m ready to commission a clean, modern portfolio website that adapts perfectly to any screen size. The single most important element is a well-designed “About Me” section where I can introduce myself and outline my skills. From layout to final deployment, I want the site to load quickly, follow best practices for accessibility, and be easy for me to update later.

Here’s the core scope I need covered:
• A fully responsive build (mobile-first, then scaling up) using HTML5, CSS3, and lightweight JavaScript or a familiar framework such as React or Vue—whichever you feel delivers the smoothest result.
• A polished About Me page with space for a short bio, headshot, and key highlights of my experience.
• Clean, semantic code and intuitive file structure so I can extend the site myself; for instance, I may add a project gallery or contact form down the road.
• Basic on-page SEO (titles, meta tags, alt text) so the site is discoverable from day one.
• Deployment to my hosting provider or GitHub Pages once we’ve signed off on the final design.

Please outline your approach, the tech stack you recommend, and an estimated timeline. I’d also love to see one or two quick examples of similar responsive work you’ve done. Let’s build something sleek that shows my work at its best.
