There are API’s hosted on middleware and proxied through Apigee which read data from ElasticSearch and output the response. There are utility jobs which read from DB2 database which form as filter values for the ElasticSearch search.

Roles and Responsibilities
• Migrated ElasticSearch from 7.17 to 8.5 which was a complete rewrite of the search implementation without which migration from on-prem to GCP would not have been possible
• Involved in requirements, design, development, unit-testing, implementation and production support
• Participated in Scrum, Sprint planning and backlog refining
• Developed the application in J2EE, Spring, SpringBoot, ElasticSearch, DB2, SQL Server, Dataflow, BigQuery
• Developed using IntelliJ IDE
• Published API for downstream applications to consume data
• Hosted the API through Apigee proxy
• Migrated the API’s that were originally on Akana to Apigee
• Validated API response using Postman
• Used testNG for accomplishing integration testing for the application and integrated the same into deployment pipelines
• Created and maintained batch jobs using spring cron scheduler
• Used GIT as version control tool
• Used Azure Devops for automated build and deployment

Technologies: Spring, SpringBoot, Java 8, ElasticSearch, BigQuery, Dataflow, Postman, JSON, MAVEN, testNG, DB2, SQL Server, GIT

• Developed the application in J2EE, Spring, Hibernate & JPA
• Developed Spring mapping classes, Hibernate annotations, JSPs, AngularJS, JQuery, HTML, JavaScript, AJAX and JSON
• Used multithreading and concurrency to run calculations of different funds at the same time to speed up the calculations and have the data available to users sooner
• Used Informatica PowerCenter to import data from external sources like database, XML file, flat file
• Used Informatica PowerCenter to export data into flat file for downstream systems to consume the data
• Developed using Spring STS IDE
• Published web services for downstream applications to consume data
• Deployed the application on tomcat STS server
