Xamarin developer to maintain and update existing app, payment integration work, conversion to MAUI
I had an excellent experience working with Karan.
He successfully upgraded our mobile application from Xamarin.Forms to .NET MAUI and handled both the mobile app and the associated .NET backend services. The project involved a number of technical challenges, but he consistently demonstrated strong problem-solving skills, attention to detail, and a deep understanding of the mobile and backend ecosystems.
Throughout the engagement, he was responsive, professional, and proactive in identifying issues before they became problems. The migration was completed smoothly, performance improved, and the application remained stable throughout the process. He also communicated clearly, provided thoughtful recommendations, and was easy to work with from start to finish.
If you're looking for a developer with strong expertise in .NET, MAUI, mobile development, and backend services, I would not hesitate to recommend him. I look forward to working with him again on future projects.
