At GNG I led the development of 4everinlove in flutter, a feature-rich dating application, and an OCR-based app designed for extracting data from EID and passport images.

I overcame challenges like ensuring 99% message accuracy through WebSocket optimization and maintaining a seamless user experience during peak usage. During the development of 4everinlove and an OCR-based app, I faced various challenges that pushed me to optimize performance and enhance accuracy.
