aayushmishramechatronics/portfolio-website ? reverse-engineered prompt

I want a clean, minimal developer portfolio website that feels modern and personal, not busy. Please build it so I can easily swap in my own name, bio, links, projects, and images, and make sure it looks good on mobile and desktop. The standout feature should be a live GitHub contribution chart pulled from the GitHub GraphQL API using env secrets, so it actually reflects the user’s activity instead of being a static screenshot.

Keep the overall design polished and simple, with smooth navigation and a professional look that would work well as a personal portfolio. If there are already pieces in the repo, reuse and clean them up instead of starting from scratch. Please make the setup straightforward, with the environment variables clearly wired so it runs locally and can be built for production without confusion. If anything is unclear, check the current docs online and fill in the gaps with sensible defaults.
