Seoul, South Korea
Summary
👤
Senior🎓
Top SchoolSungil Kang is a Site Reliability Engineer with 13 years of backend and systems experience, now working at Coupang after leading engineering efforts in mobility, logistics, and LLM-enhanced IVI features. He has driven teams of 10+ engineers and delivered high-impact services—from cutting order assignment latency from minutes to seconds to building Mapbox-based real-time editing platforms and dispatching algorithms used in smart-city pilots. His strengths span backend architecture, performance optimization, algorithm development, and pragmatic integration of LLMs into production systems. A hands-on operator, he has built high-throughput APM tooling and Python agents and frequently moves between low-level performance work and product-facing features. Based in Seoul, he blends academic depth (Master’s in Computer Engineering) with a freelancer’s breadth, having delivered diverse systems from CEX platforms to BLE attendance solutions. Contrary to the typical SRE profile, he actively ships user-facing innovations such as IVI voice search and map editing rather than only backend plumbing.
