Software engineer and Speech AI researcher building resilient, event-driven ML-powered systems.
JapanWhat I'm looking for
I’m a Software Engineer who has also become a Research Scholar at Kyoto University, working on Speech AI and NLP. I enjoy turning complex requirements into reliable systems—especially where real-time behavior, security, and scalability matter.
At ION Group, I designed and implemented an end-to-end international payment service, focusing on reliable and resilient transaction handling. I also built event-driven notification systems and push delivery infrastructure (APNs/FCM) serving 1M+ users, and re-engineered marketplace backend integrations to improve performance by 85%.
I’ve strengthened security and platform foundations through authentication and authorization workflows adopted by 10+ banks, including multi-factor authentication (2FA, OTP, RSA). I’ve also redesigned legacy Angular UI into a modular component architecture aligned with modern design systems, while mentoring junior engineers and leading onsite collaboration with global teams.
Before research, I improved production data and governance at UBS using Azure Services, optimizing Java multithreaded pipelines and supporting forecasting models for adoption of Microsoft Purview. Earlier, I explored blockchain and decentralized systems at Samsung Research and Development by building scalable Ethereum data retrieval and real-time communication reliability (99.99%).
