Harsh Khandeparkar

Harsh Khandeparkar is an independent developer whose open-source portfolio is presently anchored by Rainbow Board, a cross-platform whiteboard application that reimagines digital sketching for Linux, Windows and macOS. Built with web technologies and packaged for the desktop, the program provides an infinite canvas on which educators annotate lessons in real time, remote teams map flowcharts during sprint planning, and students work through maths equations as naturally as they would on paper. Pressure-sensitive pen support, colour layering, grid snapping and on-canvas LaTeX insertion place it alongside heavier commercial alternatives, yet the codebase remains light enough to launch from a USB stick. Because sessions are saved as compact JSON files, reviewers can replay every stroke for iterative feedback, while export to PNG, SVG or PDF preserves resolution-independent clarity for reports and slide decks. Night-owl users appreciate the adaptive dark theme, and accessibility shortcuts keep navigation mouse-free. Although still a one-title catalogue, the project’s MIT licence and active GitHub backlog signal the author’s commitment to iterative refinement driven by classroom and coworking feedback. Rainbow Board by Harsh Khandeparkar is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always installing the latest release and supporting batch installation alongside other applications.
