I need a lightweight custom web application devoted solely to entering numbers by hand. All data will be keyed in manually—no file uploads or external databases at this stage—so the interface has to be fast, responsive, and obviously restricted to numeric input only. Here’s what I expect to receive: • A clean, browser-based form that lets me add, edit, and delete numeric records, with real-time validation for integers and decimals. • A simple back-end (framework and language are up to you) that stores the values and returns them on request. • Basic reporting or table view so I can confirm what’s been entered before saving. • Clear deployment notes and commented source files so I can maintain the app after delivery. If you have a preferred stack for rapid web development—whether it’s Node.js, Django, Laravel, or something else—let me know in your proposal. Most important is that the final app loads quickly, works in all modern browsers, and makes manual number entry painless.
