I need a simple-to-use raffle draw system that can run comfortably on Windows, either as a small local executable or hosted from a browser—whichever architecture you feel will get the job done smoothly. Core workflow • I upload a list of ticket numbers and participant names from either CSV or Excel; the app must accept both formats without manual tweaks. • Before each round I set the valid ticket-number range and type in the prize on offer. • When I press “Draw”, the system selects a winning ticket at random, flashes the ticket number, name, and prize on screen in real time, and logs the result. • If the drawn ticket has no matching participant (for example, a gap in the range), I can trigger an immediate re-draw with one click. • The interface should let me run as many consecutive rounds as I like during an event. Save a screenshot of the winning ticket with date and time. Visuals & usability A clean fullscreen display for the audience is essential, with an admin panel or hotkey that lets me manage uploads, configure ranges, and initiate or redo draws without exposing the controls publicly. Deliverables 1. Complete, ready-to-run application (web package or Windows executable) with installation/launch instructions. 2. Source code and concise README so I can tweak branding later if needed. 3. Test data showing at least two successful draws and one automated re-draw scenario. If you have experience with randomisation libraries, data import modules (e.g., pandas, OleDB, or similar), and a knack for simple, show-ready UI, I’d love to see a quick demo or screenshot of previous raffle or contest projects when you send your proposal.
