Project Description: Developed a cloud-native Financial Data Distribution Platform to process, secure, and deliver market and client data across internal systems using Spring Boot microservices, Kafka, and AWS services like S3, Lambda, and DynamoDB. Integrated Cassandra and MySQL for high-performance storage, and used Kubernetes and Docker for scalable deployment and service reliability. Responsibilities and Achievements:

• Developed microservices using Spring Boot and Java 8, with Netflix Eureka for service discovery and Ribbon for client-side load balancing to distribute financial data across services efficiently.

• Implemented Kafka producers and consumers for real-time data streaming and asynchronous communication between distributed services, ensuring low-latency delivery of market/client data.

• Used AWS S3 for storing financial records, DynamoDB for NoSQL operations, and Lambda for event-driven data processing workflows in the distribution pipeline.

• Built and containerized microservices with Docker, then deployed and orchestrated them using Kubernetes, enabling high availability, scaling, and failover for critical components.

• Integrated Cassandra and MySQL to handle hybrid storage requirements: Cassandra for high-speed distributed writes and MySQL for relational operations and legacy integration.

• Utilized JPA, JDBC, and Hibernate to manage object persistence and execute complex database operations for financial reporting and tracking transactions.

• Designed REST APIs using Flask (Python) for internal data services, leveraging SQL Alchemy for ORM, while supporting microservice-to-microservice communication.

• Created and maintained REST endpoints using Spring MVC, hosted microservices on PCF, and automated deployments via Jenkins CI/CD pipelines.

• Applied Spring Security with OAuth2 for fine-grained access control and authentication across distributed APIs serving sensitive financial data.

• ReactJS for dashboard visualizations, data administration, and real-time monitoring of distribution pipelines.

• Monitored system health using Splunk and Datadog, ensuring performance tuning and early detection of data lag or process failures.

• Used Maven for build management, Selenium for automation testing, and Jenkins for orchestrating build-test- deploy workflows across multiple environments.

• Managed AWS infrastructure: configured EC2, IAM, S3, SQS, SNS, and VPCs via AWS Console and APIs, enabling secure and isolated environments for data transmission.
