I will build an interactive 3d web app or 3d product configurator with threejs


About this gig
Need a 3D experience in the browser that works on real phones, not just on a fast PC? I build interactive 3D web apps and product configurators with React, Three.js and React Three Fiber.
My own product is a 3D apartment renovation planner: a floor plan turns into a 3D model you can walk through, with wiring inside the walls, circuit calculations and a bill of materials. See the gallery and video.
What I can build for you:
- 3D product viewer for your website or online store
- Product configurator: colors, materials, parts, live price
- Custom 3D tools: planners, editors, walk-throughs
What you get:
- Fast loading with optimized models
- Works on phones, tablets and desktop, with a fallback if 3D is off
- Clean TypeScript code that you own
- Embed on Webflow, WordPress, Shopify or a Next.js site
Please message me before ordering with your 3D models (GLB, FBX, OBJ) or photos and references, so I can confirm the scope and timeline.

FAQ
Do I need 3D models?
Ideally GLB, FBX or OBJ files. If you have none, simple models can be built or licensed from libraries. We agree on this before the order.
Will it work on mobile?
Yes. I test on real phones, optimize heavy scenes and add a fallback if a device cannot show 3D.
Can you add it to my existing website?
Yes. It can be embedded on Webflow, WordPress or Shopify, or added as a component to a Next.js or React site.
Who owns the code?
You do. You get the full source code after delivery.
Can it calculate prices or quantities?
Yes. Like my renovation planner, it can count options, prices or materials based on your rules.
