What I'm looking for

I’m looking for a Data Engineer role where I can apply ETL and production support expertise, work in collaborative Agile teams, and focus on improving data reliability, performance tuning, and automation.

I am a Data Engineer with 4+ years of hands-on experience designing, developing, and supporting ETL pipelines using IBM InfoSphere DataStage across Teradata, SQL Server, Hive and Oracle environments. I focus on reliable data delivery, proactive monitoring, root cause analysis, and implementing permanent fixes to minimize business impact.

My technical toolkit includes DataStage ETL development, UNIX/Linux shell scripting for automation, SQL performance tuning, and Python (pandas) for lightweight ETL and data manipulation. I have delivered end-to-end solutions in Agile teams and supported production environments with on-call responsibilities, job reruns, and performance troubleshooting.

I bring exposure to Spark (RDDs) for large-scale processing and experience building and optimizing database objects and queries. I seek to apply my production-support mindset and ETL expertise to improve data reliability and operational efficiency.
