Summary
👤
Senior🎓
Top SchoolSeungjin Lee is a senior backend engineer with 11 years of experience building cloud-scale data platforms and distributed systems, currently serving Google Play backend teams in Seoul. He has a proven track record at top cloud providers—Google, Microsoft, and Amazon—designing high-performance APIs and large-scale data movement pipelines that dramatically cut latency and operational costs. At Microsoft he implemented graph traversal for outage impact analysis and row/column access controls that drove multi-million dollar savings; at NAVER he led a real-time logging and notification platform that reduced delays by 97% and improved client SDK throughput fivefold. Comfortable across JVM services, in-memory stores, Elasticsearch, Storm, and cloud-native services, he combines deep systems thinking with practical delivery. He also bridges disciplines via academic experience as a graduate CS reader and a business-adjacent undergraduate background in applied statistics, which informs his data-driven engineering decisions. Colleagues would note his knack for turning complex topology and access-control problems into pragmatic, measurable improvements.
