    I’m a Japan-qualified real estate appraiser and the founder of Signal Yield Advisory. I build practical AI tools and agent skills, drawing on experience in real estate investment, financing, and launching new businesses. My projects include tochi-satei-kun for Japanese land price estimation and Renotori for documenting literature searches. My goal is to help business professionals turn their domain knowledge into working software.
