Andrew Koh

Algorithm Engineer at Reolink Singapore, where I build production RAG pipelines and agentic systems, from fine-tuned retrieval and on-device inference to the evaluation harnesses that tell you when things quietly break. I hold a Ph.D. in Computer Science from NTU Singapore, with research roots in audio-language models and cross-modal learning. I write here about the interesting problems and challenges I run into along the way.
