At Samsung Research Institute, I've delivered AI-driven contextual assistance and transit payment features for more than 20 million active users. I've also expanded Samsung Wallet access to 10 million smartwatch users by migrating a legacy feature to Gear Wearable and refactoring over 10,000 lines of code.
I build reliable Android and backend systems with Kotlin, Java, Jetpack Compose, Spring Boot, and REST APIs. My automation work reduced production bugs by 15% and manual testing time by 40%, and I received Samsung's Global Professional Developer Recognition for technical contributions.
