About Me

For roughly five years, I have been actively engaged in the creation of AI-centric products and services. My experience extends beyond my role as a software engineer, as I have also taken part in project management, led small teams, and performed data analysis as a data scientist. Most recently, I have transitioned into freelancing, offering my expertise in AI system development as an independent contractor for various companies.

On this website, I write blog posts primarily about natural language processing, machine learning, and software engineering in Japanese.
