- Managed the migration of a decade's worth of customers credit card data from Oracle and MySQL to Redshift and AWS Athena. Utilized Talend ETL for extraction, transformation, and loading of data while ensuring data integrity and compliance through rigorous validation and error-checking. This improved data accessibility and analytical capabilities, reducing query response times by 40%.
- Integrated and processed financial customer data from various sources, performed transformations to streamline the data and ensure precision by eliminating inaccuracies. This resulted in simplified data integration and processing, facilitating its effective utilization for data analysis.
- Improved data processing efficiency and integrated multiple data sources into our target data warehouse by designing, developing, and deploying ETL jobs. By incorporating Azure services like Azure Data Lake Storage and Azure Synapse Analytics into our existing data pipelines achieved a 40% decrease in data processing time and ensured efficient data loading into the production environment.
- Responsible for ensuring the accuracy and reliability of customer data by crafting meticulous and comprehensive unit test cases, achieving a 98% accuracy rate in identifying data errors. Additionally, collaborated with a cross-functional team to architect and implement solutions leveraging Azure's cloud services, enhancing the scalability and performance of our data processes.
- To improve data processing efficiency and job scheduling to enhance operational effectiveness, automated processes using JIL to create and manage job schedules in Autosys, specifying job dependencies and conditions for running the jobs. This led to a significant revenue increase of $1.5M per quarter due to the enhanced data processing efficiency.
- In order to maintain high availability and reliability of our data processing operations, Utilized Azure Monitor and Azure Log Analytics to monitor job performance and swiftly troubleshoot any issues. This allowed me to keep a close eye on job performance in real-time and promptly address any issues that arose, ensuring minimal downtime and a smooth workflow for our data processing operation.
- In preparation for initiating a data integration project involving diverse sources, meticulously analyzed the initial project plan and systematically gathered crucial details to ensure seamless integration while aligning with stakeholder requirements. This effort resulted in a 25% reduction in project setup time, leading to faster project initiation and cost savings through improved efficiency.
