👋 Hi, I'm Takuya

Takuya Kitazawa is a freelance software developer, minimalistic traveler, ultralight hiker & runner, and craft beer enthusiast. With a decade of experiences as a full-stack software developer, machine learning engineer, data scientist, and product manager, I am currently working at the intersection of technological and societal aspects of data-driven applications.
