As an app developer for HMD (Nokia), I played an integral role in the development of the HMD Mobile app - a one-stop solution for managing HMD Mobile SIM plans. Working diligently alongside my team, we utilized Flutter and React to create a cutting-edge app that allows users to easily manage their account, monitor mobile data consumption, and purchase add-ons for international calls and texts, all within the app. Throughout the development process, I took charge of critical responsibilities, contributing my expertise to ensure the app's seamless functionality and optimal user experience. Being part of the team that created the HMD Mobile app was an immensely gratifying experience, allowing me to leave a lasting impact in enhancing the connectivity and convenience of HMD Mobile customers.
