iOS Engineer (Consultant)

Oct 2017 - May 2018
During my involvement in the Forex trading app project at Brisko Softwares, I played a crucial role in the iOS development. As the project was entirely new, there were no specific metrics to quantify the impact. However, I built the iOS app from scratch, leveraging my expertise in iOS development. One of my significant contributions was the implementation of in-app purchases, which was a new challenge for me at the time. I also focused on creating a visually appealing and user-friendly UI based on the provided design. Integrating the API to display real-time data for forex trading was another key task I handled. Additionally, I incorporated premium features such as news and blogs, and implemented notifications to enhance user engagement. I paid special attention to seamless transitions between UI elements, employing animations for a polished user experience. At Brisko Softwares, I worked in a small team of three members. I was solely responsible for iOS development, while another team member handled the Android side, and the third member focused on backend and design. Collaboration within the team was essential for successful project execution. One of my key accomplishments on this project was delivering it within the specified timeline. The QA process proceeded smoothly, ensuring a high-quality app. Although I did not receive any awards for this project, the successful completion and timely delivery were personally rewarding. Despite the absence of specific metrics, my dedication to building the app from scratch, implementing in-app purchases, creating a captivating UI, and delivering the project on time reflect my commitment to producing high-quality work.
