Over deze dienst
DE: Sie suchen eine maßgeschneiderte Web App, eine SaaS-Lösung oder ein CRM-System? Als deutschsprachiger Entwickler verstehe ich Ihre Anforderungen präzise und setze sie in sauberen, skalierbaren Code um.
I specialize in building high-performance Web Applications using Flutter. Whether you need a complex CRM dashboard or a subscription-based SaaS platform, I deliver solutions that drive business growth.
The Flutter Advantage: By choosing Flutter, you invest in the future. The code we write for the web can be easily adapted for iOS and Android apps later, saving you massive development costs.
What I can build for you:
- Custom SaaS Platforms: User management, subscriptions (Stripe/PayPal).
- Corporate CRM & ERP: Internal tools to manage customers and data.
- Admin Dashboards: Visualize data with interactive charts.
- Design to Code: Figma/XD to pixel-perfect Flutter code.
️ My Tech Stack:
- Frontend: Flutter Web (Dart)
- Backend: Firebase (Auth, Firestore) or REST API
- State Management: BLoC / Riverpod (Clean Architecture)
Why choose me?
- Native German Speaker: Clear communication, no misunderstandings.
- Business-First: I build tools that solve real problems.
