Roles & Responsibilities:

• Design and build API’s for Modernized application infrastructure to create bills for Member policies under P&C as per requirement specification using container managed software in cloud-based environment.
• Use Systematic problem-solving approach and software design principles to build algorithms for complex billing rules.
• Design and develop cloud-based API’s like billing mortgagee, mortgagee bill list transactions, cas underwriting pended transactions, document fulfilment services with micro services using Platform as a service (Paas) by using Kubernetes/OpenShift as orchestrator with Jboss as webserver and docker as container and AWS as Iaas.
• Define, refactor and build business services to transition from traditional, legacy platforms of existing system to service-oriented architectures.
• Build publish subscribe models to publish messages from policy administration system and subscribe it in the Enterprise billing application to create member policy accounts in real time and enable production parallel for new system.
• Implement automated, containerized cloud application by migrating workloads to containers, and integrating container platforms with automated CI/CD pipelines.
• Implement fine-tuned API security using OAuth, SAML and JWT token authorization to tokenize sensible member information and provide security to applications.
• Identify Performance bottle necks by analysing JVM heap dump and logs through App Dynamics and suggest solutions like modifying database queries which consume more time to process.
• Employ predictive modelling to identify failure of requests to Billing API's and create triggers to reprocess the same in batch environment.
• Develop virtualization API’s for external service calls like Auto or Property policy data and utilize them in building and automating integration testing using Junit EE.
• Use Business Analytics with Elastic Search and Kibana reporting to generate General Ledger reports and reconcile data between existing and new system.
• Debug System Level Deployment issues with open shift/Kubernetes, WebSphere application servers and perform root cause analysis and resolve failures.
• Use Jenkins and Jacoco tools to automate testing and develop JUnit test cases and maintain 85% of code coverage.
• Refine and groom the product backlog and user stories. Test and build automation for the API’s by coordinating with other product development teams.
• Attend design & code reviews, etc. to arrive at design patterns/ solutions and review artifacts created by team members.
• Drive offshore team by providing them required inputs on projects, helping them in understanding business requirements and system design and ensure smooth execution of project.
• Develop applications for Insurance proof of concepts using Iaas by utilizing infrastructure tools provided in AWS such as EC2 and Lambda in Java/J2EE.
