end‑to‑end.
Mid-Senior mobile engineer with 4+ years shipping cross-platform and native apps across healthcare, fintech, real estate, and IoT. Flutter/Dart at the core, with native iOS (Swift) and Android (Kotlin) depth — owning delivery from architecture through CI/CD and store release.
Profile
who / what / whyI ship real mobile products, not prototypes — owning the full lifecycle from architecture and UI through payment systems, backend integration, and App Store / Google Play release.
Most recently I built the AI feature layer for HealthWallet.me: on-device OCR for medical documents and intelligent form prefill, engineered to keep patient data sovereign by running on-device wherever possible.
My foundation is a Master's in Advanced Mechatronics — control systems, robotics, and applied AI — which gives me a practical edge on IoT and embedded integrations most app developers don't have.
On the side I founded OnStage, a church service-planning app that grew to 9,000+ users and 600+ worship teams — fully bootstrapped, from idea to live product.
Selected Work
2022 — presentOnStage
Founder · PersonalA church service-planning platform helping worship teams coordinate musicians, schedule volunteers, and plan rehearsals. Conceived, built, and shipped independently — one Flutter codebase across iOS, Android, and web, with its own backend, CI/CD, and store release cycle.
HealthWallet.me
Healthcare · AIOpen-source, GDPR-compliant cross-border medical data wallet. I built the AI feature layer — on-device OCR for capturing physical health records from the camera, and intelligent prefill that auto-populates clinical forms from captured content.
Revolut Flutter SDK
Fintech · SDKA reusable Flutter plugin wrapping Revolut's full payment suite — RevolutPay, Apple Pay, and card flows — behind one cross-platform API, so client apps get native payment and auth without per-platform implementations.
Smart Nedavi
IoT · EmbeddedMobile + IoT platform for controlling and monitoring a Chofu heat pump, with separate flows for homeowners and technicians. Real-time monitoring in Flutter, backed by Node-RED microservices for device event handling.
Retail Platform
Real estate · NativeNative iOS and Android apps for booking, renting, and managing residential properties — secure rental flows, booking management, and online identity verification enabling a fully digital, end-to-end apartment rental.
Huntex · Lendr · CSM Oradea
Social · P2P · SportsA trio of shipped consumer apps: Huntex, a native social + marketplace app for Spain's hunting community (localised, store-launched); Lendr, a Flutter peer-to-peer goods-lending app with ID verification; and CSM Oradea, a Flutter app for a basketball club's ticketing and merch.
