Client1: Marsh Inc (San Ramon, CA) Project(s): PPM and CTM Timeline: 07/2020 to Current Description (PPM & CTM):

PPM is an application designed to handle insurance-related tasks such as providing insurance quotes, comparing quotes from different vendors, renewing existing policies, and managing the billing process. To achieve these functionalities, PPM utilizes a microservices architecture, where different components or services are created to handle specific tasks. These microservices likely handle tasks such as quote generation, policy renewal, and billing management. CTM serves as a centralized repository dedicated to storing information related to colleagues/teams, accounts, placements, and profile associations. Upon receiving data from these sources, CTM processes the information and stores it in the repository. Responsibilities:

• Design and develop Microservices for various functional modules using Spring Boot, Spring security, Spring data and Google Cloud APIGEE gateway technologies.

• Developed an alternative solution utilizing Mongo change streams as an interim measure until the event-driven architecture with Kafka was fully implemented. This initiative resulted in seamless integration with UI components and was highly appreciated by the business stakeholders.

• Crafted solution to rectify incorrect and stale production data by using MongoDB aggregation queries and Spring Batch.

• Utilize a range of DevOps tools including BitBucket, Jira, Confluence, CI/CD pipelines (Jenkins/Git Actions), SonarQube, Nexus, Kubernetes, Docker, and more

• Implement publisher-subscriber models to enable asynchronous data processing leveraging Mongo change streams and event driven architecture using Kafka.

• Develop multiple APIGEE API Proxies by using various policies to consume underlying target endpoint service data.

• Design data models for request and response payloads utilizing tools such as XMLSpy.

• Responsible for creating API documentation with Swagger and sharing it to various service consumers.

• Prepare release instructions and coordinate with application support for deployment.

• As an individual contributor, I engage in end-to-end activities encompassing requirements gathering, analysis, design, implementation, testing, CI/CD deployment and documentation. Additionally, I actively participate in scrum calls, contribute to planning activities, and collaborate with support and testing teams to ensure seamless coordination.
