Over deze dienst
I am a professional Flutter & Android Developer with strong experience in Java, Kotlin, and Dart, specializing in mobile app bug fixing, maintenance, optimization, and feature development. I work with both existing apps and new projects, helping clients fix issues, improve performance, and build reliable mobile applications.
If your app is crashing, freezing, slow, unfinished, or poorly coded, I can analyze the problem and fix it correctly. I also help recover abandoned or half-built apps, refactor messy code, and make apps stable, scalable, and production-ready. Along with bug fixing, I can also build complete Android or Flutter apps from scratch using clean architecture and best practices.
Services I provide:
- App crash fixing & debugging
- UI, logic, and performance improvements
- API & third-party SDK integration
- Firebase (Auth, Firestore, FCM, etc.)
- Feature additions and enhancements
- Code cleanup and refactoring
- Completing unfinished projects
- New app development (Android / Flutter)
Tech Stack:
Flutter (Dart), Android (Java & Kotlin), Firebase, REST APIs, Android Studio.
What you can expect:
