At RoyalCApex Travel Agency, I led technology initiatives and designed and implemented mobile solutions for travel booking and operational workflows. I developed a native Android app using Kotlin and AlarmManager, with local persistence and offline capabilities for critical data.

At Dclick Soluciones SURL, I developed and maintained Flutter applications for hotel management and logistics. I added real-time package delivery updates with WebSockets and background location tracking with Mapbox.

Across my mobile work, I’ve developed Android apps with Kotlin and Jetpack Compose, and iOS features with Swift and SwiftUI. My projects include offline-first functionality, device communication over Wi-Fi and BLE, and CI/CD integrations with GitHub Actions.
