About Me

Hi, I’m Haruki Goto, a frontend engineer based in Japan. I work full-time at Univearth Inc. while also taking on freelance projects for several startups to broaden my experience and technical perspective.

Story

I’ve been interested in computers since childhood, but during junior and senior high school I focused mainly on club activities and had little chance to touch one. After growing tired of entrance exam studies, I decided to pursue a career where I could use computers creatively and started learning programming seriously after entering university. Now, I mainly focus on web development using TypeScript, React, and Next.js.

At university, I joined a robotics team where I developed robots using Python and ROS, and participated in the RoboCup Japan Open twice. Through these experiences, I learned not only technical skills but also teamwork, problem-solving, and the importance of robust error handling.

Currently, I’m primarily engaged in B2B software development, while also sharing knowledge and insights through platforms like Qiita and Zenn.
