Reduced inspection time by up to 60% in food production for quality teams at companies such as Ahold Delhaize and Aviko — by designing and building an offline-first iOS app for iPhone and iPad, using Core Data for local storage and RESTful sync on reconnection. Architected and built fully native iOS and Android apps from prototype to production, digitising daily quality registrations across the Dutch food industry — by using Kotlin Multiplatform (KMP) to unify business logic, guaranteeing feature parity and cutting long-term maintenance costs. Improved backend integration reliability and API contract consistency — by auto-generating an OpenAPI specification with 100% endpoint coverage from a Ktor-based mock server built on the same KMP framework as the mobile apps. Proactively identified and gave the backend team visibility into previously untracked API errors — by building an in-app system that delivered real-time diagnostic alerts with granular error details, enabling root-cause analysis that wasn't possible before.

Maintained stability and delivered new user-facing functionality across multiple high-traffic client apps — including Burgernet (1 M+ downloads) and Dubai Airports — by implementing onboarding flows, integrating Firebase analytics and resolving production issues. Accelerated chatbot delivery across multiple agency projects by building a reusable integration framework for the Dallas Fort Worth International Airport mobile app (100K+ downloads) — using a protocol-driven architecture and shared RESTful networking layer.

Kept Lahoux's iOS and Android apps stable and current across new OS releases — by resolving long-standing issues in a legacy Objective-C and Java codebase, redesigning the UI, and maintaining compatibility with platform updates.

Expanded support for new hardware variants — by replacing the existing media stack with a VLC-based implementation for multi-codec playback and adding RESTful API integrations for new device connectivity and media downloads.
