I have hands-on experience working with Spring WebFlux to develop reactive applications. Notably, I contributed to the creation of functional-based components for BBPayments, a payment gateway catering to multiple vendors. This involved transforming class-based components to functional-based components, enabling efficient and scalable development. Additionally, I played a key role in enhancing Reports, an application responsible for generating transaction reports for financial institutions. By converting class-based components to their functional counterparts, I optimized the application's performance and maintainability.
