During this batch I built V.A.Y.U.—a browser‑based personal operating system that I coded from scratch with HTML5, CSS3 and Vanilla JavaScript.V.A.Y.U. Goes beyond a portfolio. V.A.Y.U. Creates a real desktop feel with custom windows, movable UI parts, a clock in the top bar and apps that look and act like real ones:Desktop & Top Bar: A clean dark‑mode desktop, a translucent blurred top bar that uses backdrop‑filter, a clock that stays up‑to‑date and a wallpaper changer.Window Management System: I added z‑index layers and custom event listeners so windows glide smoothly come to the front when clicked and open or close without a glitch.Custom App Suite:V.A.Y.U. Logs (Notes App): A notes manager that builds itself from JavaScript objects with a sidebar.Tech Stack Showcase: A window that shows my tech stack and the structure of my projects.Terminal CLI: A working command line that accepts commands such as help, bio, skills, projects and clear.Sketchpad App: An HTML5 drawing canvas that lets me sketch and prototype, on the fly.Settings Control Center: A main panel where I can change the look set wallpaper cycles and check OS diagnostics.
