Built a production-grade personal portfolio using Next.js 14 (App Router), TypeScript, and Tailwind CSS. Features include an interactive particle mesh background with mouse tracking, 3D tilt effect on project cards, a Cmd+K command palette for keyboard navigation, custom animated loading screen, scrolling tech marquee, and smooth page transitions. Fully responsive across all devices. Deployed on Vercel with CI/CD via GitHub — every push auto-deploys. 🔗 tinyurl.com/vishnumashalkar
