Software Engineer
Hi, I'm mahiro.
I'm Director & CTO at Mahoroba Souken Inc., a company that develops AI and systems specialized in predictive maintenance of equipment. Predictive maintenance means detecting early signs of equipment trouble and preventing failures before they happen. Together with partners who have deep domain knowledge, such as inspection companies, we build systems such as pipe corrosion inspection AI, pump anomaly detection, and electrical leakage detection.
I love sake, sushi, and cats. 🐈
