Fullstack Personal finance app

What are you most proud of, and what would you do differently next time?

I'm proud of developing a Personal Finance App that successfully integrated various technologies and provided a smooth user experience. The app was well-received for its usability and security features, especially the use of access and refresh tokens managed with Redis.

Next time, I would focus more on planning and setting up a robust testing strategy early on. This would help identify potential issues sooner and streamline the development process.

What challenges did you encounter, and how did you overcome them?

One of the key challenges I encountered while developing the Personal Finance App was ensuring seamless authentication and maintaining security with access and refresh tokens. Initially, managing token expiration and refresh flow in Redis without affecting user experience was quite complex.

To overcome this, I researched best practices for token management and implemented a system where access tokens are short-lived, while refresh tokens stored in Redis securely handle re-authentication. I also set up automated tests to ensure that the flow works consistently. This not only enhanced security but also improved the app's overall reliability.
