In the first phase, a system was developed that provides users with a personal account to manage their financial operations. Through their personal account, users can securely make transfers, view transaction history, and manage their accounts. To ensure fast response times and high performance, a caching system was implemented, allowing large volumes of data to be processed without delays. Integration with external financial systems was also set up to facilitate data exchange, and authorization was implemented to ensure the security of all operations. Users can upload and export data in various formats while maintaining data integrity.
