Jongsang Han is a senior software engineering leader with 8+ years building scalable, DDD-driven microservices and data platforms, currently shaping data infrastructure at Korea Credit Data in Seoul. He combines hands-on Java/Spring and cloud-native expertise (Kubernetes, Helm, Kafka, Vitess) with people-focused leadership, having led engineering teams and platform migrations from Node.js to Spring. His career spans ad-tech, DSP and CDP systems where he designed batch and real-time pipelines, RTB platforms, and audience-segmentation algorithms. Comfortable operating as both architect and implementer, he emphasizes developer productivity, CI/CD, and infrastructure-as-code to keep teams focused on product delivery.
