Senior🎓
Top SchoolSunwoo Kim is an iOS-focused mobile engineer and founder with eight years of experience building consumer products and leading engineering teams across Seoul's startup scene. He has driven end-to-end delivery for Sleep AI features as Head of Engineering—owning UX, experimentation, CI/CD simplification, and production reliability—and previously shipped high-scale iOS features at Coupang and messaging platform work at SendBird. Sunwoo combines hands-on native iOS expertise with pragmatic product instincts (e.g., migrating apps to Expo-managed workflows to cut maintenance and LOC) and a track record of operational rigor in monitoring, crash triage, and rollout practices. Comfortable moving between prototyping and production, he also embeds analytics-driven decision making into product flows to measure impact by country and platform. Colleagues describe him as a responsible, hard-working founder who blends engineering depth with a restless creativity—he says he’s “always dreaming except for the moment I sleep,” which helps fuel his focus on sleep-related product innovation.
