DXC Technology•  November 2017 - July 2019

Project: Development of Managed DXC Data Distribution System DXC IT currently uses an HPE Owned/Managed integration bus – HPSB. It is a java based proprietary ESB used internally for 15 + years. HPSB supports integration, file transfer and pub- sub use case supporting SFTP, CIFS and HTTPS protocol. It uses Oracle Advance Queue for internal messaging/pub-sub/persistence layer. This project will migrate the DXC IT integration to HDF/NiFi platform. This will be a brand-new platform – hence referred as DXC DD – which will be used to support migration and will also support future integration/ingestion to Hadoop use cases. Tools and Technology Language : Java, PLSQL Duration : From November’ 17 to November ’18 OS : RHEL 7 Frameworks : Dropwizard with Swagger, Mockito, JSON, SAML2, JWT Software Tools : Eclipse Oxygen, Maven 3.5.2 Systems : Apache NiFi 1.5, Apache Kafka 1.0, MySQL 5.7, Oracle 11g, Jira Roles & Responsibilities • Developed Custom NiFi reporting task to extract, analyze the Realtime provenance data about the events and store it into Oracle 11g database • Developed Custom NiFi processors to support the get, fetch and put data operations streaming to and from Microsoft windows • Developed REST API using Dropwizard with Swagger and ZK utils library on Apache Kafka to Map the topics with NiFi data flows. • Developed Rest API Dropwizard with Swagger for Tracking to UI to analyze and presents the provenance data from Oracle Database. • Developed deployment scripts in UNIX for deploying REST API application and NAR files on servers. • Developed Oracle 11 database design and objects using PLSQL and SQL developer. • Attend and report the progress every day in scrum meeting.
