I collaborated with cross-functional teams on a recent project that involved Bluetooth, Wi-Fi, and USB technologies. First, I made sure that the requirements were clearly understood and documented. Based on these requirements, I designed the user interface and selected the appropriate database, utilizing Retrofit for API calls. I adhered to the MVVM architecture to ensure that the code was maintainable and reusable, while also focusing on code quality and performance optimization. We held regular meetings to discuss our progress and address any issues that arose. I used diagrams and examples to explain technical concepts, ensuring that all team members were on the same page. Through clear communication and collaboration, we successfully achieved our project goals.
