Saquib-Hasnain/Saquib.Portfolio ? reverse-engineered prompt

Build me a modern personal portfolio site for a backend focused full stack developer.

I want it to feel polished and interactive, with smooth animations, a clean dark theme, and a fully responsive layout that looks great on mobile and desktop. The site should introduce me, show my journey, highlight my skills, explain my backend expertise, and display featured projects in a nice way. Include sections for hero, about me, career timeline, skills, system design, experience, projects, and contact.

Please make it feel professional and geared toward someone applying for backend software engineer roles, with a strong emphasis on REST APIs, authentication, databases, backend architecture, performance, and cloud deployment. Add GitHub integration if it fits, and make sure the page is SEO friendly and easy to share. If you need to check current docs or best practices, feel free to look them up online first.
