With over 10 years of experience in IT and specialized expertise in Data Warehousing and Decision Support Systems, I have developed a strong foundation in designing, implementing, and optimizing data solutions using IBM DataStage to drive business insights. My career has been marked by significant roles where I’ve led and implemented full life-cycle data warehousing projects, helping organizations leverage their data for strategic decision-making.A key strength of mine lies in converting complex business logic into technical specifications that align with the business’s objectives. I have worked extensively on building parallel jobs using IBM DataStage, leveraging various stages like Transformer, Join, Merge, Lookup, Sort, Aggregator, various DB stages, real time stages (XML), snowflake connector, HDFS files stage etc.I am skilled in all aspects of data warehousing, including defining and implementing components such as operational source systems, data staging & data presentation. I have a comprehensive understanding of Data Warehouse principles, including the use of Fact Tables, Dimension Tables, Star Schema, and Snowflake Schema modeling, and I am proficient in both top-down and bottom-up approaches to build end-to-end data warehouse solutions.My experience spans across data governance processes, including data standardization, scrubbing, matching, and survivorship rules using QualityStage. I’ve developed custom rule sets to standardize data, enhancing data quality for critical business intelligence needs. I have been instrumental in migrating legacy ETL jobs to Snowflake pipeline processes and have worked on multiple migration projects, including upgrading DataStage components from versions 8.x to 11.x and 11.3 to 11.7. 🔑 Key Skills:ETL : IBM Information Server 8.0.1/8.1.1/8.5/8.7/11.3/11.5/11.7 (DataStage, QualityStage Designer, Director and Administrator)Databases: Oracle, IBM DB2, MS SQL server, Teradata, Netezza, Greenplum, Hadoop Bigdata, SnowflakeScripting : Korn shell scripts, pythonScheduling : Tivoli, Control M, AutosysData Modelling : Star Schema, Snow-Flake Schema, Dimensions & Fact Tables, Physical and Logical Data Modeling, Erwin (Forward & Reverse) engineeringLanguages :Java, XML, SQL,T-SQL, PL/SQL, C, C++As a data professional with a passion for innovation and quality, I’m always eager to explore opportunities that allow me to drive impactful solutions that enable organizations to harness the power of their data for strategic decision-making.
