I need a polished, professional-looking portfolio site that presents my work and credentials with the clarity and authority of a corporate profile. The build should be clean, responsive, and standards-compliant, with intuitive navigation that lets visitors move quickly from an “About” summary to individual project pages and a direct contact section. Key requirements I already have in mind: • Visual tone: professional and corporate—think restrained color palette, balanced white space, and typography that feels confident rather than trendy. • Tech stack: I’m open, but the final site must load fast, score well on Core Web Vitals, and be simple for me to maintain. Lightweight CMS solutions such as WordPress (with a custom theme) or a flat-file setup are fine as long as they deliver that performance. • Content structure: Home, About, Portfolio (with filterable project gallery), Services, and Contact. I will supply copy and images; you handle layout and any needed image optimization. • SEO foundations: clean semantic HTML, meta tags in place, and schema markup for a personal website. Acceptance criteria 1. Fully responsive templates tested on modern desktop, tablet, and mobile breakpoints. 2. Pages pass W3C validation and achieve 90+ on Google PageSpeed for mobile and desktop. 3. Editable through the chosen CMS without touching code for routine updates. 4. Delivered as a deploy-ready package with a brief hand-off guide. Tell me which framework or CMS you recommend and provide two or three portfolio links that demonstrate similar corporate-grade polish.
