Metacognitive learning and coaching app
A Visang Education Android app that offers learning courses based on metacognitive assessment. Over roughly three years, I maintained the service, developed features and incrementally migrated Java code to Kotlin.

Developing an operating learning service
The app helps learners identify what they know and follow courses at the appropriate level. I handled ongoing maintenance and new feature development.
Kotlin migration alongside operation
Rather than replacing the app at once, I moved Java code to Kotlin incrementally. I distinguished structural improvements from issues needing a quick response while continuing feature delivery.
