Hi,
Currently, I am working as a c++ QT developer, I am very good at software architecture design and I use design patterns for better architecture, I have a team having 2-3 year of experience resources, I can make a sprint for your project requirement, So we can see the burndown chart to fix the app release date , and I give unit test code for all functions and code documentation , so we can add any features to the app very easily.
Thank you
