I am familiar with many different performance and optimisation techniques that can help you to boost your business such as Bloc pattern and best UI design techniques Since the design is a visual form of communication rather than tell you about my work. I have also experience in E-Commerce app and I can also provide a prototype regarding your app with web support. I can also provide maintenance and adding an extra feature in your app whenever required. I am also providing some of my recent projects that will help you to make your decision. https://drive.google.com/drive/folders/1ElaUzTaJn8gBPhCQWLfQSKeePbceuIyn?usp=sharing Sincerely, Tushar Dubey
