Top SchoolMyeongjin Song is a backend engineer with 10 years of experience building high-performance, AWS-native systems using Java, Spring, Node.js and serverless technologies. At Samsung SDS he designed and operated common backend platforms for a 1M-active-member system and a logistics service used by 12,000+ companies, improving auth latency from 200ms to 50ms and search throughput to sub-300ms. He combines hands-on DevOps with architecture work—designing ECS/NestJS frameworks, DynamoDB+OpenSearch pipelines, Lambda SnapStart optimizations, and resilient DLQ/retry flows.
