Profile
Hello! I am Takuya Matsuyama, a web engineer at Fukui Computer Co., Ltd., where I develop full-stack web applications using ASP.NET Core, TypeScript, SQL Server, and Azure. I completed my master's degree at the Graduate School of Frontier Biosciences, Osaka University, where I researched brain function elucidation using Vision, Audio, and Language AI at the Nishimoto Lab.
