Experience
Software Developer
Mastercard - Missouri
• In Mastercard project, I have led and contributed to several key projects, including the migration of legacy Java applications to newer versions, which involved optimizing the codebase for performance and maintainability. I also developed and implemented feature toggles to manage combined payloads dynamically within services, ensuring backward compatibility and seamless deployment. • Additionally, I worked on handling version-less payloads, enhancing system flexibility and reducing integration complexities. • My responsibilities extended to the payment card brand identifier project, where I streamlined the identification process for various card brands, improving transaction accuracy and processing efficiency. These experiences demonstrate my expertise in modernizing applications, enhancing service architecture, and ensuring robust system operations. • Another critical aspect of my role involved decommissioning outdated APIs, ensuring a smoother transition to modern frameworks and reducing technical debt. • Designed and implemented Splunk dashboards to monitor and verify API data, identify duplicate transaction keys, and track data transformations to DOMO. This improved data visibility and operational efficiency. • Participated in scrum meetings and collaborated with Business Analysts to translate business needs into functional designs, developing solutions through business models, logical specifications, and user requirements. • Experience in Core Java and implementing concepts such as OOPs Concepts, Garbage Collector, Collection Framework, Generics, Exception Handling, I/O System and Multi-Threading. • Enhanced logging mechanisms to capture detailed application events, aiding in troubleshooting and performance analysis. Addressed performance logging issues, which led to faster identification and resolution of bottlenecks, improving system reliability.
