Summary

What I did

• 3D Product Configurators — SaailMorph & KitCAD: Built SaailMorph’s modular GLB/material/rule-driven configurator architecture and KitCAD’s procedural kitchen CAD (CSG, snapping) in React + Three.js.
• Event / Expo Digital Twins — LIMA 2025 & AWS Tech Summit: Contributed MapLibre/Mapbox + Three.js venue layers, POIs, routing, and LLM-powered assistants/discovery (e.g. Gemini) on shared digital-twin frontends.
• Airport Indoor Maps & Routing — Changi Airport: Contributed to MapLibre-based indoor map/routing clients handling complex spatial layers and turn-by-turn navigation flows.
• ACRE 3D — Real Estate Virtual Tour Platform: Owned major UI + Three.js authoring/viewer flows (GLB upload, hotspots, aerial/ground modes) and wired AWS/3ds Max render-pipeline touchpoints.
• Operational Digital Twins — SmartBuild, AirOps 360, SkyView: Contributed React/Vue frontends combining Three.js/MapLibre/Mapbox views with IoT/ops analytics UI and AI-assisted operational queries.
• 360Works — WebXR Builder & Viewer: Owned React + R3F + WebXR builder/viewer implementation with interactive scenes and frame-accurate media sync.
• VizualTravel / TravelXR — 3D Travel Itinerary Visualizer: Implemented multi-mode path generation/animation (directions APIs), MapLibre camera movement, and Three.js model sequences.
• Prezerv — 3D Construction Planning Platform: Worked in Cesium/Potree stack; fixed map and business-logic bugs blocking a reliable demo.
• Indoor Maps Platform: Contributed authoring (draft→publish), offline maps for poor connectivity, analytics dashboards, and venue apps (e.g. Gardens by the Bay, Art Basel).
• Groomio (FUR4): Built scroll-driven R3F product showcase hitting ~60fps across 16 screens.
• EventSphere (IDECS): Contributed expo navigator with 2.5D maps, engagement flows, and Gemini AI assistant integration.
• Buildings History (UK): Integrated MapLibre + deck.gl extrusions/markers/terrain for historical building cataloguing.
• Set The Table: Shipped React + Three.js training minigame in ~22 hours.
• 3D Model Texture Optimizer: Built texture fetch/optimize/analytics flow to reduce WebGL asset weight.

Results

• Real-time configuration at ~60fps with reusable variation systems instead of one-off hard-coded product viewers.
• Shipped LIMA 2025 on a rapid timeline and AWS Singapore Summit’s 2.5D portal for talks/booths/schedules.
• Production navigation experience deployed for Changi Airport.
• End-to-end web tour product path from model upload → authoring → interactive delivery.
• Operational twin demos/dashboards for iconic SG facilities, airport ops visualization, and Flyer IoT monitoring.
• Production WebXR platform openable in browser / Quest Browser.
• Stabilized Prezerv demo delivered in ~10 days.
• Reusable indoor-maps capabilities supporting multiple venue/event frontends in React and Vue.
