Summary
👤
Senior🎓
Top SchoolWen-tsung Chang is a Staff Software Engineer with 11 years of hands-on experience building resilient cloud-native infrastructure, SRE practices, and backend systems from Taipei. He has led large-scale migrations and optimizations—most notably driving a company-wide Kafka migration that cut costs by 83% and reworking CDN and observability layers to drastically reduce latency and operational overhead. Proficient in Kubernetes, Istio, Fastly VCL, and operator-driven platforms, he consistently converts complex distributed systems into low-maintenance, cost-effective operations. He also architects automation (IaC, node-local DNS caching, cross-account ECR caching) and rapid DDoS mitigation APIs that keep services robust under stress. An avid teacher and organizer, he runs study groups and internal training (Kafka, Kubernetes, Go) to elevate engineering-wide capabilities. Outside work he channels the same intensity into discovering heavy music, a passion that mirrors his preference for energetic, high-impact problem solving.
