Mobile wallet for offline crypto payments.

Team formation: We assembled a dedicated team consisting of specialists with specific roles: 1 iOS developer, 1 Android developer, 1 QA specialist, 1 Project Manager. 

Requirements gathering: A thorough requirements gathering phase. We collaborated closely with the client to define project objectives, user stories, and acceptance criteria. 

​​​​​​​Technology selection: After careful consideration, Native Android (Kotlin) and Native iOS (Swift) were chosen as the development languages due to their close integration with device capabilities, which is crucial for implementing features like NFC and secure payments. 

Mobile development: The development team begins building the mobile application simultaneously for iOS and Android platforms. Development sprints are organized to work on specific features and functionalities. 

User feedback: Gathered through Agile/Scrum events like DEMOs, where all stakeholders were invited to view and provide feedback on new functionalities and features. 

Integration with financial partner: During the development of the mobile app, we have worked to ensure seamless integration with the financial partner's systems to provide secure and convenient payment solutions for the stores. 

​​​​​​​Source code management: A robust source code management and version control system was implemented to facilitate collaboration and maintain code integrity. 

Quality assurance: Unit testing, integration testing, and user acceptance testing to identify and address any issues promptly. 

Security testing: To ensure the highest level of security, we collaborated with a third-party for regular security testing — involving penetration testing and vulnerability assessments to fortify the system's security. 

​​​​​​​Staging and testing environments: Firebase is leveraged for Dev and Test environments, enabling quick sharing of builds and providing valuable analytics and crash information. 

Deploy process: We employed a semi-automated deployment process, covering multiple environments including Development, Testing, and Production. 

Production rollout: The final production rollout is executed through the native app stores of Apple and Google, ensuring a seamless and controlled release to end-users. 

​​​​​​​Compliance: Throughout the deployment phase, we ensured compliance with relevant industry standards and regulations, particularly regarding financial transactions and data security. 

Client collaboration: We maintain an ongoing collaboration with the client's Product Owner, who leads the way in prioritizing and approving system features. 

​​​​​​​Monitoring and optimization: Post-deployment, the system is continuously monitored for performance and user feedback. Regular updates and optimizations are made to enhance the user experience and system efficiency.
