About this gig
Need more than a regular website? I build custom interactive web applications that users can click, explore, calculate, compare and use.
I can create interactive SVG floor plans, clickable maps, custom calculators, pricing tools, comparison widgets, galleries with lightbox, embedded maps, sticky navigation and responsive layouts.
Everything is hand-coded in HTML, CSS and JavaScript. No bloated builders, no unnecessary plugins and no lock-in. You receive a fast, lightweight and self-contained project that you fully own and can host anywhere.
This gig is perfect for real estate websites, rental space brochures, office or venue maps, product configurators, pricing calculators, interactive landing pages and custom web tools.
I take every project seriously and carefully turn your idea into a clean, modern and functional interactive experience. Message me before ordering so I can understand your idea, confirm the scope and recommend the right package.

FAQ
What counts as an interactive web app?
An interactive web app includes features users can click, explore, calculate or compare, such as SVG maps, floor plans, calculators, galleries, pricing tools or comparison widgets.
Do you use WordPress or website builders?
No. I build everything with clean HTML, CSS and JavaScript, so the final project is fast, lightweight and not locked into a builder or plugin system.
Can you work with my floor plan, SVG file or Excel data?
Yes. You can send floor plans, SVG files, Excel data, prices, room statuses, images or other materials, and I can structure them into the app.
Will the app work on mobile devices?
Yes. The project will be responsive and tested on desktop, tablet and mobile before final delivery.
What do you need before starting?
I need your idea, content, images, data, files, brand style and a clear explanation of how the interactive feature should work.
