Dana Justip
Justip is a cross-platform eCommerce application that offers a meticulously curated collection of unique items from various cities and countries. It serves as a global marketplace, catering to a wide variety of consumers. At its core, Justip operates on a unique business model where sellers act as intermediaries, facilitating the purchase of products from providers on behalf of consumers who may be unable to visit the desired locations themselves. This innovative approach introduces a new level of convenience and accessibility to the shopping experience.
Developing a real-time chat application with seamless communication between sellers and buyers presented significant technical challenges. Ensuring real-time synchronization across devices and managing concurrent user interactions required intricate solutions.
Additionally, reproducing and resolving production issues, understanding intricate technical nuances, and overcoming setup and configuration hurdles for specific features posed considerable obstacles during the testing and development phases.
To address the real-time communication challenges, our team leveraged Firebase's real-time database, implementing efficient data syncing mechanisms and optimizing network communication. Scalability considerations, such as efficient data structuring and handling, were also prioritized to support a growing user base while maintaining performance.
Collaborative efforts between QA engineers, developers, and the project owner played a pivotal role in navigating through obstacles. We adopted a systematic problem-solving approach, which involved comprehensive analysis of project requirements, regular feedback collection, and active engagement with stakeholders.
