This custom trading application was developed to provide users with real-time financial analysis and trading capabilities on mobile devices. Built using Xamarin and integrated with the NinjaTrader platform, the app offers traders comprehensive charting tools, technical analysis indicators, and automated trading options. The app’s responsive design ensures a seamless experience on both Android and iOS, allowing traders to monitor and execute trades on the go. My role included designing the application architecture, developing the core trading functionalities, and integrating secure data feeds from NinjaTrader. With SQL Server as the database backbone, the app ensures fast data retrieval and secure transaction handling, delivering a 25% increase in user engagement and real-time trading efficiency.
