Software Developer

Responsibilities:

• I actively contributed towards product development DaaS building data as a service platform and was responsible for building RESTful WebServices, Visualization, GateIn Portal Customization and Configuration, JBoss AS 7 administration, Building MyBatis Mappings, and JMX Mbeans, User Registration Services, Relevant JUnit test cases,JavaScript,XML, CSS, HTML5 JQuery, JSTree, AMCharts, Tableau, D3JS for Portlet Navigation, Search and Display as per JSR 286 portlet specifications, Data Modeling and ETL tools like SQL Power Architect and Informatica Power Center.
• I have contributed towards introducing the concept of Linked Data and Federated Queries using DB2 Information Integrator,Infoshpere DataStage, OpenLink Dataspaces and further customization for leveraging SPARQL to exploit Semantic Web to leverage public data and leveraging Hadoop Pig and HiveQL for unstructured data from both internal and external sources to be integrated into the architecture of DaaS platform.
• Data Modeling, Profiling tools SQL Power Architect and ETL implementation Informatica and Custom or capturing meta-data of ETL transformations and data profiling for data quality and DDL generation.
• The primary goal was to enable users including analysts to rapidly build and test queries from sample data for any business objects built using custom sandboxes for analysis using the business glossary and data-dictionary terms of enterprise metadata and link them to diverse data-sources RDBMS and HDFS and make then allow the federated data engine to extract data and then transform and load such open data into RDBMS for further analysis and create RDF links in the semantic web to enable users to discover applicable services and other relationships between those terms and entities.
• I have also contributed in customization of both versions of this product for demonstration at the Federal Communications Commission and also it has been successfully adopted at the Internal Revenue Service, where Computech provides Data Strategy for these both clients.
