Built and shipped Voyager, a white-label rider app used by 50+ transit agencies (including New York MTA, National Express, Metrolink). Delivered the app across web, iOS, and Android using a single Nuxt (Vue 3) + Capacitor codebase. Led frontend feature work including onboarding (configurable multi-step instructions), push notifications, and PCI compliance via an iframe approach to keep cardholder data separated from integrators’ systems. Achieved WCAG 2.1 AA compliance across the application. Implemented SDK logic in Kotlin to format data and apply brand-specific behavior using feature flags.

Developing a web & mobile application focused on public transportation using Nuxt.js, Capacitor.js, and Flutter.

Scaled and modernized the core e-commerce platform for kfzteile24 (Germany’s leading car parts retailer). Completed a phased migration from legacy Twig (PHP) to Vue.js using a strangler pattern so old and new code could run side by side. Led migration from Vue 2 to Vue 3 and Vuex to Pinia, restructuring shared logic into reusable composables and adopting a repository file pattern for a single source of truth and reduced duplication. Built a Playwright E2E test suite covering ~130 critical user flows and integrated it into the CI/CD pipeline to block faulty deployments and reduce production regressions.
