Summary
👤
Senior🎓
Top SchoolSim Xue is a Full Stack Software Engineer based in Singapore with nine years of experience building scalable, user-facing systems across game studios and large tech firms. He has shipped production features at scale—from WebSocket IM infrastructure that handles a million monthly active users and 5x faster messaging, to interactive playable ads with 100M+ impressions—using a mix of Golang, TypeScript, Unity/C#, AWS, and Redis. At companies like Habby, Sea, Indeed and Shopee he has owned end-to-end services including SDKs, backend platforms, and mobile frontends, often bridging product, design and ops to deliver measurable engagement improvements. A Computer Science student at NUS, he pairs strong systems and API design skills with a game-development mindset for rapid prototyping and iterative optimization. Less obvious: he frequently tackles cross-domain problems—from identity and alerting systems to playable ad performance tuning—making him adept at both backend architectures and player‑facing experiences.
