Senior🎓
Top SchoolHanna Lee is a backend developer with nine years of experience building scalable, production-grade services for consumer platforms in Seoul. She has driven backend features at Kakaobank, Lotte Healthcare and Influential—shipping mission-driven gamified health services, enterprise health-check integrations, and high-throughput event systems for audio and ebook platforms. Proficient in Kotlin, Spring WebFlux, Python/Flask and event-driven architectures (Redis, RabbitMQ), she repeatedly reduces DB load and operational risk through asynchronous designs and pragmatic automation. Hanna adapts quickly to new stacks—learning and applying Kotlin, Webflux and reactive patterns to launch time-sensitive products—and pairs that technical curiosity with a disciplined habit of daily PRs and continuous learning. Notably, she blends backend engineering with product thinking, having implemented reward/mileage systems, challenge engines and resiliency measures that improved both performance and user engagement.
