How to Go from a Quick Idea to an Essential Feature in Four Steps

This post details the initial development of GrabChat, a real-time in-app messaging feature. It covers the problem identification (challenging internet conditions in Southeast Asia), the MVP solution development (starting with a simple TCP server and evolving to a service-oriented architecture with a dedicated message exchange service), and the evaluation of its impact on cancellation rates using statistical analysis and a cancellation prediction model. The protocol design prioritized client-side message loss handling to optimize server resources. The iteration phase highlights the addition of template messages to improve driver usability.
