Letās jump on a quick call to discuss your roadmap and how I can help you scale.
Steps for completing your project
After purchasing the project, send requirements so Javed can start the project.
Delivery time starts when Javed receives requirements from you.
Javed works on your project following the steps below.
Revisions may occur after the delivery date.
Project Source Code Access
I require access to the Xamarin project source code. Once access is successfully granted, I will conduct a preliminary review of the code base before commencing the migration and development work.
Migrate Xamarin Code to .NET MAUI
Upon receiving source code access, I will begin migrating the Xamarin code to .NET MAUI. I will ensure the application is fully functional, I will implement the MVVM pattern and Dependency Injection to ensure the system is loosely coupled if possible
