About this gig

I specialize in migrating legacy applications (.NET, Android, iOS) to Flutter cross-platform architecture with clean, scalable backend integration.


If your app is outdated, difficult to maintain, or built on legacy code, I will modernize it while preserving business logic, APIs, and database structure.


Full Android/iOS to Flutter migration

Legacy .NET system modernization

Clean architecture & modular codebase

API integration & backend restructuring

Firebase / custom backend integration

Performance optimization & refactoring

Production-ready, scalable delivery


I dont just convert code I rebuild it with maintainability, scalability, and performance in mind.

Ideal for startups, enterprises, and businesses upgrading their mobile ecosystem without disrupting backend systems.


Portfolio Highlights:

AI-powered Flutter apps with backend integration
