   Architected and implemented core services, using the latest Java 17 and Java 18 versions. Designed services with both synchronous (HTTP/gRPC) and asynchronous (Kafka, RabbitMQ) communication patterns, enhancing the system’s scalability and resilience to support high user loads during peak times- Integrated the IBS Core Banking System with both new and existing microservices, facilitating seamless real-time data flow across FIS platforms. Improved data consistency and reduced latency for customer account updates and transactions by leveraging AWS SQS for reliable asynchronous messaging and Redis for low-latency caching- Established observability best practices for Digital One and Horizon by implementing Prometheus for metric aggregation and Jaeger for distributed tracing, reducing mean-time-to-resolution (MTTR) through advanced alerting and visualization. Configured Grafana dashboards for real-time monitoring of key performance indicators- Led backend development for the Digital One Omni Channel project, creating high-performance microservices in Spring Boot to support unified customer experiences across mobile, web, and ATM channels. Optimized service architecture to achieve a 30% reduction in response times through efficient load balancing, enhanced data caching, and gRPC-based low-latency communication- Leveraged cutting-edge Angular technologies, including Angular 14 CLI for streamlined development, Angular Material for elegant UI components, and RxJS for reactive programming, to architect and develop dynamic single-page web applications that offer responsive, performant, and user-friendly experiences- Adopted a Test-Driven Development (TDD) approach, implementing robust unit, integration, and end-to-end testing frameworks using Cucumber for BDD, Jest for JavaScript/TypeScript unit tests, and Selenium for functional testing, achieving high test coverage and early issue identification.
