Developing a highly secure, scalable, and user-friendly application for storing sensitive user data, including biometric information, presented significant challenges. Ensuring robust data protection while maintaining seamless authentication processes was crucial.
The project also required integrating complex technologies like Docker, MongoDB, and third-party biometric APIs, all while achieving modularity and maintainability in the codebase. Balancing data protection, system performance, and user experience posed a significant challenge in this development.
