• Worked on analyzing duplicate records and fixed bugs in provider details for CCDA. Supported query changes related to provider codes, retry logic for webservices
• Automated data profiling for CCDA parsed data using Java to build new tables which helped other projects to get results faster.
• Automated validation dat checks for schema field names against data frame using Java.
• Made changes to Data Quality Rules dat are applied to CCDA messages.
• Worked on publishing rejected messages to Kafka topics using Scala
• Worked on retrieving thousands of PDFs dat are sent to ECMS team. Optimized Scala code and shell script code dat generated meta xml and PDFS.
• Worked on resolving the count discrepancies between meta xml and PDF files using Java and generated necessary PDFs on strict timelines.
• Optimized shell script code to pull and push data to hdfs. Initial code were making the process was running slow and also effected the other processes running in the cluster.After the changes job was able to run much faster.
• Developed process to load historical data received from ECMS team using Shell Scripting and Spark Sql.
• Understood the code written in Java which was used to send messages using kafka. We also needed to understand the dependencies for Serialization and deserialization and access from our code.
• Developed code to write Kafka Consumer using Scala to consume, deserialize data to specific record.
• Parsed deserialized data for 6 Schemas and pushed to HDFS using Scala generics concept.

Technologies: Java, REST, Spring MVC, Spring JPA, Spring Boot, Apache Kafka, UML

Responsibilities:

• Wrote queries in Spring JPA to access database in SQL Server 2008.
• Implemented Rest Web Service using Springboot. Used Junit to test the web service APIs.
• Implemented Apache Kafka Consumer to receive the request in JSON format.
• Worked on embedded Kafka to unit test Kafka consumer. Also used console based producer to test the consumer.
• Worked on Angular 2 to write the components to display the data, used HTML5, CSS3 to design the front end such as bid period details based on the selected bid period. The components displayed the data sorted in ascending and descending order.
• Worked on an application which was containerized using docker. Wrote the Jenkins job to execute the build script to build angular 2 and Springboot code. Served Angular2 code from an nginx server within a docker container.
• Used two AWS Linux instances. One instance had Jenkins job which pulls the latest code from GitHub, builds the angular2 and Springboot Code, creates the images and pushes them to DockerHub. Used Publish over SSH plugin to send the docker compose file over to the other instance and wrote the build script commands dat would pull and run the images in the second instance.
• Used port forwarding in Windows to run docker containers.
• Worked on deploying a in-house project using MongoDB on docker.

• Transformed, validated and processed incoming SOAP messages for partner requests for various parts of the reservation process including pricing, booking, modify using Apache CXF, XSL, Spring Integration.
• Wrote Spring Integration flows which passed messages through components such as chains, channels, routers, gateways, service activators. Service activators invoke validators to validate the response received. Composite and service layer calls are made as part of the chain .The service layers are responsible to call the external Amadeus web service to get the response.
• Worked on merger XSLs to merge the request sent with the response received in order to maintain all relevant data throughout the flow.
