About this gig
I will build a custom interactive web widget that turns your idea into something people can actually use on desktop and mobile.
Choose one focused tool such as:
Calculator or estimator
Quiz with automatic scoring
Random name, idea or challenge generator
Spin wheel or random picker
Countdown or progress tracker
Interactive checklist
Simple decision tool
Stream or community widget
You receive a polished responsive widget, editable HTML, CSS and JavaScript source files, clear usage instructions, testing and one revision. It can run as a standalone page or be embedded where your platform allows custom code.
Before delivery I test desktop and mobile behaviour, calculations and inputs, accessibility basics, exposed secrets, unsafe dependencies, injection risks and common configuration issues.
This gig covers one clearly defined front-end tool. Hosting, domains, user accounts, databases, payments and paid third-party services are not included. Message before ordering if the widget requires an API, login or integration.

FAQ
What do you need from me?
Send the exact tool idea, inputs, rules or formulas, desired output, style and colours, wording, examples and where it will be used.
Can I embed it on my website?
I deliver standalone files and embed guidance. Compatibility depends on whether your website platform allows custom HTML and JavaScript.
What does testing include?
I test desktop and mobile behaviour, input edge cases, formulas, accessibility basics and practical security checks. This is not a formal penetration test.
