This is a case study for one of our clients, Nicholas Nedelisky, who approached us to conduct a review of the Foodiaz system. The app has a beautiful product design, but he was confused and frustrated by the numerous bugs and performance issues that were affecting the user experience.

After conducting a thorough review of the Foodiaz system, we identified several technical issues related to performance, security, and scalability. Specifically, we found that the app was built with an older version of Flutter that did not include Non-Null-Safety, leading to potential crashes due to invalid data being received from the backend. Input verification was also non-existent, which could cause crashes if empty fields were sent from the frontend to the backend. Security issues were also present, such as poor DNS management and user input not being validated on the frontend, which could result in dirty data being sent to the backend.

From a scalability perspective, the app was not developed with scaling or robust maintenance in mind. The app lacks load balancing, which can cause performance issues when handling a large number of requests. There is also no caching mechanism implemented, which can slow down the app when it needs to retrieve data repeatedly. Furthermore, the app does not have a scalable database structure, which means that the system may not be able to handle a large number of users or data growth.

We recommended a technical solution to address these issues, including migrating away from Flutter and building the app in a lightweight language and framework such as Next.JS, implementing horizontal scaling with microservices architecture, and implementing load balancing and caching mechanisms. Nicholas subsequently engaged a new development team to address these issues, and we are currently monitoring their progress.

Overall, we believe that these technical improvements will greatly enhance the performance, security, and scalability of the Foodiaz system, providing a better user experience and laying the foundation for future growth and success.
