During March 2025, Aygnep developed a user engagement metric feature for the NKU-WIKI/wxapp repository, focusing on tracking and displaying total likes across user posts. Leveraging JavaScript, cloud functions, and database management, Aygnep implemented an end-to-end solution that calculates total likes via a new cloud function, synchronizes data between the backend and local cache, and updates the frontend UI to present real-time engagement insights. This work enabled both users and business stakeholders to monitor overall post engagement efficiently. The feature was delivered with traceable commits and demonstrated depth in metrics instrumentation, data consistency, and seamless integration across the application stack.
