What I'm looking for

I'm an immediate joiner seeking remote or hybrid roles, and I can align with European working hours.

At Aezion Technologies, I designed and supported ETL/ELT and data-ingestion pipelines using Azure Data Factory, ADLS Gen2, and Azure Databricks. I built PySpark transformations and applied Delta Lake patterns for incremental processing and upserts.

I improved pipeline efficiency by using source timestamps and watermarks to reduce unnecessary reprocessing. I also optimized Spark workloads through partitioning, broadcast joins, caching, and other performance techniques.

For the Healthcare Data Platform project for Samaritan Ministries (SMI), I supported REST/JSON API ingestion, Salesforce integration, and incremental extraction. I also handled production troubleshooting and data validation, and used Git and Azure DevOps for source control and deployment workflows.
