I will develop a widget for comparing internet provider tariffs by address

I design and build widgets for comparing internet provider tariffs that determine connection availability by specific address. A website visitor enters the street, building and entrance, and instead of a general list of all city operators, the widget shows only those companies that can actually connect this specific building, and immediately compares their tariffs by speed and cost.

At the core of the solution is an address normalization module, verification against each provider's coverage database and a matching mechanism that filters out unavailable options before showing results. Next comes sorting: by price per megabit, by total monthly cost or by promotion value. I design the interface so it integrates into an existing website without design changes: an address search field, results as a table or cards, filters by connection type (fiber optic, cable, wireless internet) and a button to proceed with ordering for each tariff.

What is included in typical work:
— address input field with suggestions and validation
— logic to determine available providers based on your coverage database
— sortable comparison table with speed, price and promotions
— responsive layout for mobile devices
— management panel to update tariffs and coverage zones without code changes

I work with any source of coverage data — from a ready database to a spreadsheet export, and can supplement the widget with an application form or conversion tracking for each offer.
