At T7 International Group, I architected and developed a digital pet management platform, with backend microservices in Java and Spring Boot and native apps in Jetpack Compose and SwiftUI. I implemented geolocation and alerting, real-time chat, and Stripe payments.

At Ualá, I migrated fintech app UI modules to Jetpack Compose and applied MVVM architecture with dependency injection. I improved maintainability and the investment module UX while completing the transition without impacting product stability.

At BanRegio, I led a 10-developer team and coordinated bi-weekly releases from implementation through app store publishing. I also defined technical solutions, mentored junior developers, and applied Clean Architecture and MVVM.
