Chong Kang Rui

I've built full-stack e-commerce and AI customer-support platforms using React, Next.js, Node.js, PostgreSQL, Stripe, and Google Gemini. My projects focus on production concerns such as concurrency-safe checkout, idempotent Gmail ticketing, layered backend architecture, CI/CD, and automated testing.

At Insense Studios, I designed procedural level generation, AI and interaction systems, and real-time gameplay loops for a VR game, while improving rendering performance from 30 to 72 FPS. Previously at Nimbus Games and as a freelancer, I built multiplayer, gameplay, AI, inventory, and extensible weapon and ability systems in Unreal Engine.
