Building and redesigning Settlement service for Visa (Distributed model) by interacting with different services through kafka producer/consumer model. Using IBM db2 as backend to save aggregated data which will be settled with EOD closing window event followed by report generation for Issuer/Acquirer.

Working on designing solution for engineering team in a pre-build stage by collaborating with system architects.

Working with Open VisaNet team which is one of Visa's Key initiative that will help Visa support in-country processing solutions and provide Visa an opportunity to move away from Proprietary Mainframe type systems. It is built as a modern distributed architecture based on micro services with goals of five 9’s availability, fault tolerance, horizontal scalability and real time latency for largest scale transaction processing.

Specific technologies I am working on includes developing Domain Specific Language compiler in Java Xtend Framework for Evaluating DSL Rules which would generate go files upon successful compilation.

Also worked on writing transaction specific tasks like Merchandise return, CAVV, Stand in processing in Golang. Also, implemented Filecollector, Fileprocessor services as well as monitoring the activities on Grafana dashboard by creating different metrics.

Developed an internal Gherkin-based tool for the team which will enable developers to auto generate cucumber feature files. The tool UI was developed in ReactJs and backend was supported with Neo4j database.

The tool was helpful in creating multiple scenarios and complex conditions instead of writing it manually
