Led the effort to migrate the reporting old legacy stack to a more simpler, less maintainable and scalable platform based on NodeJS. Implemented database query generator to generate queries dynamically based on different flavors of database(vertica, snowflake and druid).Led and delivered the migration of the reporting back end system interaction from multiple data sources to cloud(snowflake). Worked on the reporting real time data driven user interface used by external clients for getting the insights of their inventory.Worked on a proof of concept on Redis for caching in reporting team. Led and designed the industry based REST APIs using swagger for the simplified platform for reporting by unification of multiple stacks. The swagger tool helped in validating the request and response. The new set of APIs are based on OpenAPI standards and also support multi tenancy.

• Extensively worked on Restful API design and implementation.• Designed and implemented Object model or collection required for storing the user state in mongo DB.• Productionalize the interaction between the restful application and mongo data store.• Implemented the first compliance policy required for the target scope of countries. • Key role in taking the UT Coverage to 95% and worked on bug fixes.• Used spring framework for application development.• Integration with external components (REST APIs)• Got the spot award for single handedly leading the effort for rolling out the several countries

 Developed a module for extracting or disintegrating huge legacy code in C by modifying the C grammar using ANTLR. The module parses the C file and decomposes the code into different atomic units which can be run in a parallel fashion. These atomic units are saved in cloud and can be reused to make new applications. The application is a finite state machine with the atomic units as states of the machine.  Implemented multithreading to run the atomic units in a parallel fashion.

The project was to automate the insurance system by calculating the risk, premium of the person based on his age, habits, developed service modules using Accelerator framework, a customized framework based on JSF. Integrated log4j in the ANT build scripts for the application.Converted a module from Struts to Java Server Faces(JSF) framework.Developed Defect tracking system for logging defects using JSF
