Software Engineer
Hi, I'm mahiro.
I work as a backend engineer at a major tech company in Japan. My main responsibilities include designing, developing, and operating microservices and API Gateways using Go. I'm leaving my current job at the end of August and joining a new company in September. I love sake, sushi, and cats. 🐈
