While the technical details are impressive, the contact page reveals a smaller attack surface with no contact form, directing users directly to email. This might feel less convenient for some who prefer a structured submission process. Additionally, the site currently runs no analytics, though it mentions future plans for privacy-first Google Analytics 4. For a professional portfolio, the absence of a direct contact form is a minor usability hurdle, though email remains a fast alternative.
The available information highlights a strong command of modern frontend technologies. Andrew Cheung utilizes Next.js 15 with React Server Components to keep client-side JavaScript lean, ensuring faster load times. His work incorporates TypeScript strict mode, Tailwind CSS for design tokens, and Zod for API input validation. The inclusion of Web Vitals and a custom canvas 2D dot grid instead of heavier libraries like Three.js demonstrates a commitment to performance efficiency. This detailed tech stack suggests a developer who is well-versed in creating fast, accessible, and secure user interfaces for large-scale products.
