Build me a personal portfolio website for Rahmat Aditya with a subtle pixel art dark theme, mostly black and deep blue, that feels modern but playful.

I want a landing page with a hero section that has a typewriter style role text and a starry animated background, then clear sections for about me, projects, certificates, skills, and contact. The projects, certificates, and stats should load from a backend API, and the certificates should open in a modal so people can view the file without leaving the page.

Make it fully responsive, smooth to scroll, and polished with light animations. Include a contact form, social links, a simple footer with a moving tech marquee, and a clean navigation bar. Use React and Vite, and feel free to look up current docs online if you need to. Keep the design elegant, subtle, and easy to browse on desktop and mobile.
