The development of banking systems has evolved from legacy, traditional systems to contemporary digital systems that utilize innovative technologies for greater efficiency, security, and convenience. This paper discusses the design, implementation, and performance assessment of a Spring Boot Banking System, a scalable and secure platform for conducting banking operations. The platform's system implements the Spring Boot framework to secure a solid backend framework, along with Spring Security for safe authentication and JWT for authorization. It includes features of user registration, account maintenance, transaction processing, and admin controls.The system was tested in terms of performance, scalability, and security, and the findings indicated quick processing times for transactions, support for a high number of concurrent users, and safe management of sensitive user information. The solution proposes to overcome the shortcomings of legacy banking systems through a contemporary, user-friendly interface with increased security features and support for scaling according to the expanding needs of financial institutions.The study also suggests potential enhancements in the future, such as integrating mobile banking, AI-based fraud detection, and researching blockchain to verify transactions. The Spring Boot Banking System provides an overall solution to contemporary banking issues and is thus a desirable tool for banks to innovate and enhance their online banking solutions
