Summary
👤
SeniorSeung Han is a software engineer with eight years of professional experience building high-performance backend systems for gaming, telecom, broadcasting, and DoD clients. He specializes in Java and has evolved his stack to include Python, Kotlin, Spark, Flink, Kubernetes, and Kafka for cloud-native, distributed workloads. Known for improving API and system performance through caching, multithreading, reactive streams, and careful data synchronization (Oracle ↔ MongoDB via Kafka/GoldenGate), he designs resilient microservices and real-time processing pipelines. At NAVER and prior roles at Rakuten and LINE PLAY he shipped scalable game and travel services, authentication flows, and admin tooling that relied on Redis, RabbitMQ, and Kafka Streams. Comfortable in Linux-based production environments, he also brings low-level systems experience (serial protocols, packet segmentation, large-file transfer) that informs his approach to performance and reliability. Outside production code he enjoys visualizing data—drawing maps and charts to explore system behavior and research insights.
