Need a digital twin, 3D venue map, or Three.js app that stays fast in the browser? I'm a Top Rated (100% JSS) tech lead building airport, expo and building digital twins, WebXR tools and 3D configurators. Most 3D web projects don't fail on visuals. They fail on architecture: dropped frames, fragile prototypes, and spatial logic that breaks as the product grows. I design and build the foundation so your 3D product can scale. SELECTED WORK (much of it delivered with my team at Saailverse) Digital twins & indoor navigation • Multi-floor turn-by-turn indoor routing for a major Asian international airport • Airport passenger-flow simulation replaying 364 days (~70k departures) of real schedule data on MapLibre • Real-time crowd intelligence for a 55,000+ capacity stadium, using camera feeds and IoT sensors • Digital twin for landmark buildings: 3D models, CCTV, live IoT data and AI analytics in one dashboard • IFC/BIM building models integrated on MapLibre maps (BIM + GIS in the browser) Event & venue maps • Digital twin and 3D map portal for a national aerospace & maritime expo, delivered in under 6 weeks for thousands of attendees • 2.5D venue map with chatbot search for a major tech summit, used by thousands of attendees 3D configurators & visualization • Browser kitchen configurator: procedural cabinets, CSG countertops, precision snapping, 60fps • Modular 3D product-configuration platform: hierarchical variations, rule engine, live WebGL preview • Real-estate virtual-tour pipeline: GLB upload → in-browser authoring → automated cloud rendering (3ds Max on AWS) → interactive aerial and interior tours • Browser-based 3D flexible-office visualization for a global commercial real estate firm (Babylon.js) WebXR & immersive • Lead WebXR developer on a 360° VR/AR training builder and viewer: React Three Fiber, frame-accurate video sync, desktop, mobile and headset modes • Worked on an open immersive web engine for multiplayer XR across desktop, mobile, VR and AR • Gamified VR color-exploration experience for a paint brand "Muhammad served as our lead WebXR developer... he never once missed a milestone." (Albert P., 5.0 stars, 360Works) HOW I CAN HELP • Architecture & technical leadership: I own the technical direction from planning to deployment, without piling up technical debt. • Three.js / WebXR audit & rescue: I find performance bottlenecks, memory leaks and architectural flaws, and hand you a concrete roadmap. • End-to-end build: React / Next.js / TypeScript front ends, Three.js / React Three Fiber / WebGL, MapLibre / Mapbox / Cesium maps, Node.js / AWS backends. STACK: Three.js, React Three Fiber, WebGL, WebXR, React, TypeScript, Next.js, MapLibre, Mapbox, Cesium, Babylon.js, Node.js, AWS, GSAP Send me your project goals and I'll reply within 24 hours with a strategic technical assessment.
