Christian V.

Flutter Developer | MVP Builds, App Rescues, Subscriptions

Top Rated Plus Flutter dev. 20+ apps shipped, 100% Job Success. I build MVPs, rescue stalled apps, and set up subscriptions that actually convert. Most of my work goes beyond basic UI: RevenueCat and Stripe subscriptions, Firebase or Supabase backends, BLE hardware, maps, push notifications, and App Store / Play Store releases. I've taken apps from napkin sketch to launch, and I've stepped into half-built codebases and shipped them. I'm usually the right fit when a project needs someone who can understand the product, sort through the moving pieces, and make steady progress without every detail spelled out. What I can help with: - Building MVPs from idea to launch - Fixing, taking over, or cleaning up existing Flutter apps - RevenueCat, Stripe, and in-app purchase setup - Firebase, Supabase, PostgreSQL, auth, storage, and realtime features - BLE / Bluetooth hardware integrations - Maps, GPS, and location tracking (Mapbox, Google Maps) - Push notifications, analytics, AI integrations, and store deployment - Release planning, QA support, and technical direction Tech I use regularly: Flutter, Dart, Firebase, Supabase, PostgreSQL, REST APIs, RevenueCat, Stripe, Mapbox, Google Maps, BLE, OpenAI, BLoC, GoRouter, iOS, Android What clients have said: "Christian is an extremely engaged, proactive and capable engineer. I recommend working with Christian if you get the opportunity!" "Christian had no problem hitting the ground running with an existing team on an app that was partially built, and delivered immediate value. Fast turnaround, creative solutions." "He was able to quickly assist our urgent requests and provided valuable input. I highly recommend Christian." If you're building, fixing, or trying to finally ship your app, send me a message and I'll help you figure out the cleanest path forward.
