About Me

Who I Am

Wong Kai Wey (Kelvin)

I'm a solutions-focused AI & Full-Stack Engineer based in Kuala Lumpur, Malaysia, with a proven track record in bridging business needs with advanced AI and software development. I specialise in designing and implementing robust, scalable solutions — including LLM integration and Retrieval Augmented Generation (RAG) architectures — to automate complex workflows and eliminate data processing bottlenecks. Trilingual in English, Chinese, and Malay, with a First Class Honours Bachelor of Computer Science in Artificial Intelligence.

AI Integration

Building RAG pipelines, LLM-powered features, and intelligent search experiences that make data useful at scale.

Full-Stack Development

End-to-end product delivery with Next.js, FastAPI, and cloud-native infrastructure — from DB schema to production deploy.

Problem-Solving

Translating ambiguous requirements into clean, maintainable systems. I care about the 'why' as much as the 'how'.
