Explanation: Partnered with a design agency to overhaul a legacy client landing page. My focus was on converting a static HTML/CSS design into a modular Next.js structure with Tailwind CSS, prioritizing SEO and Core Web Vitals (achieving 90+ across all metrics on mobile). Integrated complex Framer Motion animations for smoother interaction, leading to a 25% increase in sign-up conversions. Proved that a pixel-perfect, fast UI drives real business results.
