In 2003, I joined NTT Data Co., Ltd. and was involved in the development and operation of mission-critical system for mobile internet services. In 2014, I shifted my focus to the financial sector, where I was responsible for building large-scale derivative trading system for exchanges and risk management solutions for securities firms. Additionally, I served as an auditor for NTTDATA ABIC Co., Ltd. As a project manager, I worked on projects such as financial risk management solutions and personal data trust bank assets development. I also contributed to the provision of trade platform services utilizing blockchain technology. Starting in October 2023, I became a founding member of Progmat Co., Ltd.
