🎓
Top SchoolGaram Choi is a data engineer with 8 years of experience building high-throughput backend services and video-understanding AI pipelines, primarily in Java and Kotlin while also coding in Python, JavaScript, Go, and recently contributing Rust to open source. He has designed and optimized APIs serving millions of users at Kakaobank (~1000 TPS), reduced latency through async processing and caching, and automated manual workflows to cut administrative time from hours to minutes. His background spans database query engines (Apache DataFusion contributions), frontend, web scraping, and browser automation, reflecting a pragmatic full-stack curiosity. Comfortable across cloud and on-prem stacks and open to global remote roles, he blends hands-on implementation with performance-first architectural thinking.
