At Crest Infosystems Private Limited, I design and maintain ETL/ELT pipelines with Python, PySpark, SQL, AWS, and Microsoft Fabric. I’ve automated data ingestion from APIs, SFTP, databases, email, and cloud storage, and developed cloud-based processing solutions for financial, loan processing, and mortgage analytics projects.
I also build interactive Power BI and Amazon QuickSight dashboards and implement data quality checks for reliable reporting. On a project, I built an event-driven pipeline that extracts Excel attachments from Outlook emails and ingests them into AWS S3, eliminating manual data collection effort.
