Usman A.

Let your customers customize your products, see every change in real time, and move straight to a quote or purchase. I build interactive 3D product configurators, browser-based sales tools, and Unreal Engine experiences that help businesses explain complex products and make buying decisions easier. I’m Usman Ahmed Abbasi, an Expert-Vetted Upwork professional and Co-Founder of Darul Solutions & LetsConfigr. I bring 15+ years of experience, backed by a studio with 500+ completed projects. My core specialty is connecting realistic 3D visuals with the logic behind your business: product options, compatibility rules, pricing, quotations, and e-commerce workflows. WHAT I CAN BUILD FOR YOU ► 3D Product Configurators — Three.js / WebGL Give customers the freedom to explore and personalize your products directly in their browser. • Change colors, materials, finishes, and components • Select accessories with compatibility rules • Update pricing as selections change • Rotate, zoom, and explore product details • Add animations, hotspots, and annotations • Save and share configurations • Request a quote or add configured products to cart • Connect Shopify, CRM systems, and custom APIs Suitable for automotive products, furniture, jewelry, sheds, industrial equipment, and other customizable products. ► Configurator SaaS Platforms Turn your configurator into a platform your team, dealers, or customers can manage. • Company accounts and user permissions • Product catalogs and configuration rules • Pricing and asset management • Subscription and license management • Admin dashboards and analytics • Domain licensing and API integrations ► Unreal Engine 5 & Interactive Archviz Help buyers explore a property or product before it exists. I develop interactive architectural walkthroughs, real-time product presentations, virtual showrooms, and digital twin interfaces, with features such as material switching, lighting controls, guided navigation, and interactive information. ► VR Training & Simulations Create hands-on experiences where users practice tasks and interact with equipment. Applications include assembly and disassembly, industrial procedures, safety training, education, and enterprise demonstrations. ► 3D Assets & Optimization A polished experience also needs to perform well. I create and optimize real-time assets using efficient geometry, PBR materials, GLB/glTF, compressed textures, and web/mobile performance workflows. I can also add AR product previews where they support your customer’s buying journey. HOW I APPROACH YOUR PROJECT We start with your product, users, and business workflow—not just the visual reference. I help define the configuration rules, review your existing 3D assets, and select the right technology for your target devices and delivery requirements. Development covers the interface, 3D interactions, integrations, testing, and deployment. You work directly with me on technical direction and delivery, with studio support when the scope requires additional modeling or development capacity.

Send me your product details, a reference example, and any existing 3D models or CAD files.
