I need a clean, professional portfolio site that positions me convincingly in front of potential clients and employers. The design language should lean corporate rather than artsy: balanced whitespace, restrained colour palette, crisp typography, and a layout that feels reliable and authoritative on both desktop and mobile. The heart of the site will be a set of detailed project case studies. Each case study page must allow room for a narrative, key metrics, supporting images, and a clear call-to-action so visitors can contact me or request more information without hunting for a form. Beyond the case study section, I will also need: • A concise home/summary page that quickly conveys who I am and the value I bring. • An about page with space for a short bio and professional headshot. • A contact page with a secure form routed to my email. Please build on a platform I can update myself—WordPress, Webflow, or another reputable CMS is fine so long as editing text and swapping images stay straightforward. SEO-ready structure, fast load times, and responsive testing across modern browsers are essential. When you reply, tell me which CMS or stack you recommend for a corporate-style portfolio, how you would structure the case study template, and your estimated turnaround time from kickoff to launch.
