Available to hire
I am a Senior Android Engineer with nearly 15 years of experience delivering reliable, high-performance mobile apps for South Korea, Singapore, Malaysia, and global remote teams. I specialize in Kotlin, modern Android architectures, and end-to-end delivery, mentoring small squads and collaborating closely with Product and Design to ship practical solutions used by millions of users. I’ve driven SDK integrations, module migrations, and feature ownership across large cross-functional teams, with a proven track record of improving app performance, crash rates, and user retention. I’m also exploring AI-driven mobile features through side projects at the proof-of-concept level and applying AI where it meaningfully enhances the user experience.
Beyond coding, I enjoy mentoring engineers, aligning work across multiple squads, and facilitating strong engineering discipline in highly regulated environments. I’m motivated by building robust, scalable mobile platforms and by collaborating with product and design to deliver meaningful impact for users and partners.
