At M&T Bank, I build Java microservices for real-time transaction processing and connect them with AWS to support banking workflows.
I also built CI/CD pipelines with Jenkins and Docker, and designed RESTful APIs connecting legacy mainframe systems with mobile banking features.
For M&T Bank, I implemented OAuth and Spring Security protections and developed JUnit and Mockito tests for core banking services.
At Walmart, I developed Java microservices for retail transactions and connected them with Kafka for real-time inventory updates. I also built React and Redux interfaces for the checkout experience.
