大学院まで機械工学を学び、株式会社リコーにてRICOH GR等のカメラ設計を経験の後、bird and insectの立ち上げに参画。映像業界では珍しいEvangelist（エバンジェリスト）として、専門知識やノウハウを分かりやすく体系化・翻訳して皆様にお伝えするのが役割。Youtubeやイベントによく出没。SNSでは愛猫（虎太郎）の力を借りて人間では角が立つような本音を語ります。

After graduating from grad school with an emphasis on mechanical engineering, Hayashi worked at Ricoh and was involved in the design processes of cameras such as the RICOH GR. He then took part in the launching of bird and insect. As a rare “evangelist” in the image&film industry, Hayashi’s goal is to systematize and simplify expertise knowledge and share it with everyone. He can often be seen on Youtube and at various events. Hayashi also shares his insights on SNS with the help of his beloved buddy cat, Kotaro.
