What I'm looking for

I'm looking to build reliable backend systems, solve complex production and performance challenges, and lead cross-functional delivery while continuing to grow in AI, computer vision, and machine learning.

I'm leading delivery of large-scale ticketing, membership, and reservation systems for Japanese clients at SPLUS-SOFTWARE JSC, while contributing to backend development, technical investigations, and production issue resolution.

I've built backend services for reservation workflows, seat allocation, payment processing, ticket lifecycle management, and administrative operations using PHP, Java, Python, SQL, RESTful APIs, and GraphQL. I also optimize database operations, review code, assess technical impact, and coordinate releases across cross-functional teams.

Previously at WEAI Technology, I developed a multi-tenant educational platform with isolated organization data, classroom management, and online testing. I designed RESTful APIs, built database-level tenant separation, and deployed services with Docker and AWS.

Alongside software engineering, I research computer vision and UAV object tracking. My published work proposes an enhanced YOLO and DeepSORT-based framework for reducing ID switches and improving tracking stability during occlusion.
