keshabpadhan/keshabpadhan.github.io — reverse-engineered prompt

Build me a polished personal developer portfolio website that works as a simple static site using just HTML, CSS, and JavaScript. I want it to feel dark, modern, and a little flashy, with glassy cards, neon cyan and purple accents, an animated background, and smooth scroll reveal effects. Please include sections for home, about me, skills, projects, education, coding profiles, achievements, and contact. Make the top navigation sticky, highlight the active section while scrolling, support mobile with a hamburger menu, and add a scroll progress bar plus a back to top button.

In the hero section, add a typing style intro and clear buttons for contacting me and downloading my resume. The contact area should validate input, let people copy my email easily, and fall back to opening their email app if direct form sending is not set up yet. Please make the whole site responsive, accessible, and easy for me to replace placeholder content with my real projects, photo, resume, education, and achievements. Look up current docs online if you need to.
