What I'm looking for

I’m looking for a Data Engineering role where I can own ETL and API integrations, modernize data workflows, and ensure dependable TAC-driven production orchestration—with strong standards, governance, and team collaboration.

I’m a Data Engineer focused on building end-to-end ETL development, data ingestion, and schema optimization in enterprise environments. In my recent role, I managed large-scale data migration projects from Oracle to Hive while maintaining high data integrity and performance, and I delivered ingestion from sources like MS Access SQL, Oracle, SharePoint, and flat files into big data ecosystems.

I specialize in Talend-based API testing and ingestion frameworks, designing Talend jobs to enable seamless data exchange between platforms. I also strengthen operational reliability by troubleshooting and resolving complex orchestration issues for jobs running in Talend Administration Center (TAC) production, optimizing ingestion jobs for data cleansing, new line issues, and unknown character values, and supporting BAU through rigorous Hive SQL data validation.
