Senior Mobile Engineer & Technical Lead

View My Website • Connect on LinkedIn • Email Me

I'm a Senior Mobile Engineer and Technical Lead with 8+ years building apps used by millions, including Avis Budget Group (car-rental giant, 15M+ users), UOB (one of Singapore's largest banks), Scoot (a Singapore-based regional airline), and BRI (Indonesia's largest state-owned bank). I ship production apps across the full mobile spectrum: native Android, iOS, Flutter, and React Native. I have led migrations across that spectrum: Java to Flutter, eight apps into one React Native codebase, and now legacy Kotlin/XML and Swift/UIKit into Jetpack Compose and SwiftUI.

• Led the rewrite of 8 apps into one codebase for Avis Budget Group's car-rental suite, used by millions of renters worldwide: native and Flutter apps across NAM/APAC and EMEA consolidated into a modular React Native platform.
• Migrated BRI's Ceria personal-loan app (5M+ downloads on the Play Store) from legacy Java to Flutter, speeding up feature delivery and cutting infrastructure costs.
• Kept flight operations running for Scoot Airline: built the vOCC Android app used daily by pilots, ground staff, and ops managers for mission-critical flight operations.
• Accelerated delivery at Azendo with an AI-assisted, spec-driven workflow powering the incremental Ledoc rebuild into Jetpack Compose and SwiftUI.
• Founded and ran a software consultancy (Venragroup Technology) for four years, leading product delivery while building and mentoring a cross-functional team.
