About this gig
Custom Interactive Product Builders for Shopify & Custom Sites
If you sell bespoke items like cakes, furniture, or apparel, your customers need to "see" their choices before they buy. I build high-end, interactive product configurators that turn a boring static form into a premium, interactive shopping experience that drives massive conversions.
Why My Custom Builders Beat Templates:
- Shopify & Custom Integration: I specialize in building "headless" configurators that plug directly into Shopify liquid or any custom React/HTML site.
- Vanilla JS Performance: No slow plugins or heavy frameworks. Your tool will be ultra-fast (0.7s load time), SEO-friendly, and secure.
- Luxury GSAP Animations: I use GSAP to create smooth, high-end transitions that build instant brand trust and a "luxury" feel.
- Complex Custom Logic: Multi-step configurations tailored to your business rules (e.g., Step 1: Material -> Step 2: Color -> Step 3: Size).
- Mobile-First Design: Fully responsive layouts that work perfectly on all devices, from desktops to smartphones.
What You Will Get:
- Clean, optimized source code (HTML, CSS, Vanilla JS).
- Interactive UI components that increase your store's average order value.
- Fast-

FAQ
Do I need to buy hosting or a domain first?
Not necessarily! I specialize in high-performance deployment using Netlify, which offers a free tier for many custom sites. If you already have a domain, I can help you connect it. If you are using Shopify or WordPress, I can integrate the builder directly into your existing setup.
Why should I choose a custom builder over a standard plugin?
Most plugins are "bloated" and slow down your site, which hurts your Google ranking. By using Vanilla JS and Tailwind CSS, I build a tool that is lightning-fast, secure, and fits your brand's design perfectly—something a generic plugin can't do.
Will this work on mobile devices?
Absolutely. Mobile shopping is the priority. I use modern CSS techniques (like Tailwind CSS) and GSAP to ensure the interactive experience is just as smooth on a smartphone as it is on a desktop.
