I joined web development company, LIG Inc., as an intern during my third year of university. After graduating, I officially joined the company in 2015. With a passion for writing and a desire to become a professional writer, I became an editor involved in managing LIG's owned media, which had a monthly traffic of 4 million PV at the time. Later in 2016, I joined the DevRel team, and when the team transitioned to an independent company called dotstudio Inc., I followed along. At dotstudio, I contributed to the operation of media platforms focusing on IoT-related content.

During my time at LIG Inc., I became close with a senior colleague who was a Chief Engineer. Through our conversations, I developed an interest in web development, leading me to create my own website through self-study. The challenge of creating a website where the screen changes exactly as I inputted intrigued me, as even a small mistake would result in no change on the screen. This simplicity and complexity of web development fascinated me, motivating me to deepen my knowledge in the field. In August 2018, I joined BRISK Inc., a web development company, as a Front-End Engineer, where I utilized HTML, CSS, JavaScript, PHP, and other tools to create various web projects.
