Turning Ideas into Reality

I'm Ambati Lalitha Sagar, a B.Tech Information Technology student at Aditya College of Engineering and Technology. I'm passionate about building real-world projects and apps that solve everyday problems.

From Progressive Web Apps with offline support to peer-to-peer file sharing and attendance tracking systems, I love taking an idea from concept to a live, working product. I enjoy combining frontend craftsmanship with cloud-powered backends using Firebase, Node.js, and modern web APIs.

I'm always exploring new technologies and building things that matter — one project at a time.
