Project description:
"I need a lightweight web-based answer sheet designed specifically for examinations. The key requirement is a digital whiteboard area where candidates write their subjective answers by hand with a stylus, exactly as they would on paper. As soon as the student lifts the pen, every stroke should be stored securely and rendered back with perfect fidelity when the script is opened for marking.

The flow I have in mind is straightforward: a student launches the exam, the timer starts, and the blank answer sheet appears. They write directly on the canvas, scroll for extra pages, and submit when finished. Invigilators then open the script online and see the handwriting just as it was written, with the option to download a clean PDF.

Core deliverables
• Interactive canvas/whiteboard that supports pressure-sensitive stylus input, unlimited undo/redo, and smooth scrolling for multiple pages.
• Auto-save and final submission endpoints (REST or GraphQL) so no work is lost if the connection drops.
• Marker view that replays strokes or shows the final image with zoom and pan.

I’m open to the front-end stack—HTML5 Canvas, [login to view URL], React, or any equivalent library—as long as the handwriting feels natural and latency is minimal. If you have existing work on exam tools, or ideas for future additions like automatic grading of objective sections or lightweight cheating-prevention hooks, please mention it."
