After graduating from university, I joined Geo Technical Laboratory Inc., where I developed measurement vehicles and conducted commissioned research on travel time prediction using automotive probe data, managing a team of approximately 10 members as both Project Manager and Engineer.
I was seconded to ZENRIN Co., Ltd. for two years, collaborating with their employees on research and software development. Subsequently, I engaged in map utilization research for BIM/CIM and deep learning research projects, working as a Project Manager and Researcher on automatic map generation projects.
I then joined DATAFLUCT Inc. as a Data Scientist, working on data utilization projects. While maintaining side jobs at DATAFLUCT and FastLabel Inc., I joined The Harmony Inc. as a Senior Engineer, developing conversation robots for dementia patients. In the latter half of my tenure, I also served as Project Manager and Product Manager alongside my engineering responsibilities.
Currently, I work at PKSHA Associates Inc., focusing on launching HR domain initiatives and implementing AI features in RPA products, specializing in 0→1 phase development. From February to November 2025, I contributed to GEOTRA Inc. as a side job, developing a people flow data analysis platform that combines GPS location information with machine learning technology. Additionally, I run my own business developing access control systems for 24-hour gyms and smartphone usage detection systems using security cameras.
