Senior🎓
Top SchoolYoushin Cho is a backend engineer with 8 years’ experience building scalable, cost-efficient systems across Tokyo’s consumer tech scene. Currently at AbemaTV after impactful backend roles at MUSINSA and STYLESHARE, he has delivered real-time migration pipelines, a cost-optimized personalized recommendation system, and an S3 Object Lambda image resizing solution that cut CDN costs dramatically. He pairs strong distributed-systems chops (Kafka Streams, gRPC, OpenAPI) with pragmatic DevOps practice—leading GitOps migrations, batch infra revamps, and Elasticsearch indexing pipelines. Notably, he reduced API latency by half during a large-scale region migration and engineered on-demand image compression achieving 98% reduction. Comfortable across polyglot microservice environments, Youshin blends performance tuning with developer experience improvements and a knack for turning operational pain points into automated, production-ready solutions.
