Design & development of Spring Integration based service to communicate information between VC++ based system with 3rd party REST API and Microsoft Azure Service Bus via Tibco EMS.

Role & Responsibility

• Analyze 3rd Party API and Azure Service Bus data flows and design a data structure to filter and transform data between API and VC++ client.
• Collaboration with Client Developer to communicate, design, plan and implement requirement changes.
• Develop codebase for the service.
• Development of Test bed for System Integration test that can perform testing with dynamic data sets.

Achievements

• Picked up Spring Integration on the job and built up significant expertise of the framework within 4 weeks of project initiation.
• Received multiple client appreciations for successful delivery cycles with client recommended technology stack and framework.
• Continuous Integration setup in client CI-CD (Jenkins) environment.

Design & development of Spring based system to analyze operational data flow between client and their partners for identifying and correcting data discrepancies.

Migration of Microsoft Access DB based standalone application to web based distributed system and integrate with client portal.

Build a responsive web portal to report real-time daily/monthly operational/performance KPI for client executives to plan future operational efficiency.

Role & Responsibility

• Analysis of existing system to identify KPI calculation algorithms.
• Design REST Service, communication format and develop JAX-RS based service to expose determined parameter values to responsive UI.
• Collaborate mockup design of responsive layout in with web designer.
• Development of Struts based J2EE backend for responsive UI and communication channels with REST service.
• Functional testing, deployment and warranty support.

• Develop a highly available, high performance concurrent system that can process data from multiple different systems in reasonable time.
• System should be able to withstand database failureand continue operation without it affecting normal processing.
• System should be able to replay processing after recovery from database failure.
• System should be able to report transaction failures between integrated systems to human POC automatically.

Role & Responsibility

• Fully responsible for development, testing and delivery of all modules.
• Collaborate with Principal Architect regarding requirement changes, system design updates, technology stack determination etc.
• Technical documentation including Functional Spec, UI design, Service Contract design etc.
• Distribution of tasks to team members, tracking progress and quality of delivery periodically.
• Report risks and delays to project manager, onsite coordinator and revise plan and schedule post changes to requirements.

Achievements

• Delivered 100% bug-free code to production despite numerous requirement changes, resource re-allocation etc.
• Delivered final System with a 100% performance growth on expected/agreed numbers by implementing a highly concurrent system.
• Received multiple appreciations from client for above expectation deliveries.
• Built a file-system based custom caching solution for handling database failures due to client limitations of using existing caching solutions like ehcache, infinispan.

Worked on various web projects and middleware applications based on Struts, jQuery, EJB, JunitEE, SOAP services etc. with solo responsibility of requirement understanding, technical stack decisions, design, development, testing and deployments.

• Worked for maintenance and support on Internal Compliance systems of a leading US based Insurance provider.
• Worked with Struts, Adobe Flex, IBM Filenet and various Java/J2EE technologies for day to day maintenance and support activities.
