Responsive Portfolio Site Build

I need a frontend developer to bring my personal portfolio online with a bold, colorful aesthetic. The site must look and feel great on phones, tablets, and desktops, loading quickly and guiding visitors smoothly through the content. Tech stack is set: pure HTML, CSS, and JavaScript—no frameworks this time. Build it with clean, well-commented code so that future tweaks are straightforward. Core requirements you’ll tackle: • Fully responsive layout that keeps the vivid color scheme intact on every screen size. • Contact form wired for easy message delivery (vanilla JS validation, no page reload). • Intuitive navigation and lightweight assets for fast first paint and smooth scrolling. I’ll provide copy, imagery, and color references once we kick off; you handle structure, styling, and interaction. Clear progress updates and the occasional screen share will keep us aligned. Deliverables considered complete when: 1. All pages pass Google Lighthouse mobile performance ≥90. 2. Contact form sends and confirms successfully. 3. Codebase (HTML, CSS, JS) is handed over in a tidy repo with brief setup notes. If this sounds like your kind of build, let’s get started. Budget: USD 250–750
