Summary
Yu Sawai is a software engineer in Kyoto with 14 years of experience combining NLP research and production ML/data engineering, currently building text-understanding and generation services for advertising at CyberAgent. He blends a solid research background (MS from Nara Institute) with hands-on systems work from Nikon—spanning anomaly detection, HPC administration, and data engineering—so he’s comfortable from model prototyping to deployment. His day-to-day mixes roles as an NLP-focused data scientist and ML systems developer, applying linguistics-informed techniques to practical ad-serving problems. Colleagues might know him as the “low-res tuxedo cat” of SWE—steady, adaptable, and quietly prolific—and he brings a mechanical-engineering mindset to complex modeling and infrastructure trade-offs.
