Claudius dev / Services
A mobile app needs a dependable service behind the screen. We build the app and its backend together, with attention to account flows, subscriptions, device integrations and the work involved in releasing and maintaining it.
Work directly with Claudiu Sfetan, from scope to release and support.
Discuss your projectReact Native and Expo applications shaped around the tasks people return to. We identify the essential journeys first, then agree the devices and platforms the release must support.
Accounts, backend APIs, subscriptions and device capabilities where the product needs them. Integrations are scoped around the actual user experience, including loading, denied permissions and failure states.
Release preparation, testing and submission support, followed by an agreed maintenance scope. Store approval depends on the platform review; we account for that process in the launch plan.
Feel Bloom provides a public App Store example with subscriptions and HealthKit integration. WEGO, a marketplace Claudiu built and operates, includes customer, driver, kitchen and operations apps connected to the same delivery platform.
A cycle-aware wellness app that turns a morning check-in into a plan for the day, available on the App Store.
I built the mobile app, subscription flow, marketing site and admin console, then took the app through App Store review. Daily plans bring together meals, workouts and a wind-down, with HealthKit integration and custom visuals. The admin console supports content management and analytics.

A food-delivery marketplace I built and operate on the Costa del Sol, connecting customers, restaurants and drivers.
The platform covers the delivery workflow: ordering and payments, restaurant preparation, driver assignment and operations. I built the storefront, dashboards and backend, plus customer, driver, kitchen and operations apps that share a mobile design system. Dispatch combines location data with a Python service for assignment optimisation and preparation-time and arrival estimates. I handle releases and operate the infrastructure myself.
