🧭 Camp View (RexinTech – My Startup)
Built and led as part of my registered startup RexinTech, this 3D Campus Navigation System uses GeoJSON and AI pathfinding to deliver real-time routing on an interactive map. Secured seed funding and tested in live campus environments. -
🏛️ Singapore National Museum Project
Developed the backend system for an internal photo request platform used by museum staff and external researchers. -
🤖 Offline AI Assistant
A fully offline RAG-powered personal assistant with file upload, vector indexing, and custom file-based memory — built for privacy-first LLM use cases. -
🎓 GASC Sync
Role-based college management system with dashboards for admin, staff, and students — includes circulars, bonafide approval, and searchable public forums. -
✋ Touchless – Hand Gesture Control System
Virtual interface using MediaPipe + OpenCV for controlling the mouse, scrolling, volume, and drawing via hand gestures. Modular and mode-switchable. -
🔥 Fire Vision (ForgeofCreations - Startup)
Contributed to a low-light fire detection system that uses real-time camera frames for safety which primarly focuses on installing it in existing cameras. Assisted in backend integration and deployment planning for device streaming.
