Senior🎓
Top SchoolRayner Lim is a software engineer and product-minded technologist with 8 years’ experience building developer platforms, AI-driven systems, and full-stack products. He bridges engineering, design, and business goals—having shipped internal tooling and LLM-driven automation at TikTok that improved DX for thousands of engineers and built a TypeScript error-fixing pipeline using the TypeScript Compiler API. As a solo founder at Ziva AI he designed a conversational product-discovery assistant with a dynamic fuzzy-state conversation engine and non-technical “scenario cards,” shipping a full-stack system from crawler to embeddable chat widget. Now at Sierra as an Agent Engineer, he continues to focus on empowering engineers with platforms and automation, drawing on a rare blend of product design training and hands-on systems engineering. He also brings operational rigor from prior mission-critical systems experience in the Singapore Armed Forces, which informs his pragmatic approach to reliability and scalability.
