Raised in India during childhood. While in high school, completed a marketing internship at AdGlobal360 India Pvt. Ltd, a subsidiary of Hakuhodo Inc. in New Delhi, India. During the internship in India, visited Google India and developed an interest in programming. Passed the final screening of a long-term engineering training project called “Techprenour DOJO” during the summer vacation of the first year of university. Also selected as a scholarship student for the Silicon Valley scholarship sponsored by Pegasus Tech Ventures, a pioneer in CVC 4.0 funds, during the winter of first year of university. Served as the 53rd chairman of the Waseda University-approved computer research club, WINC.

From the spring of second year at university, they were responsible for the web backend development of “RanQ” using golang and clean architecture at Forstart Co., Ltd. From the summer, they concurrently led the development of the front-end and back-end of the native app “Andu” using Flutter at Wyn Co., Ltd. and led the development of the subscription function. They also worked on the overall development of “Arcle” in collaboration with a student organization at Musashino Art University.

They studied programming on own and developed more than 20 apps in total. Among them, the student-limited SNS app “Gakucha,” which was developed in two weeks, has now achieved 180,000 downloads. They continue to develop and operate apps within their hobby range alone, including the NFT user-oriented SNS “Crypties” and the matching app for solo diners “Bocchi Meshi.”
