What I'm looking for

I’m looking to lead and own Azure data engineering projects—building reliable Databricks/Delta pipelines, improving performance and data quality, and automating operations end to end in an engineering culture that values clean debugging and continuous delivery.

I’m an Azure Data Engineer with 9 years of IT experience, including 8 years building production-grade data pipelines on Azure Databricks, Azure Data Factory, and PySpark. I take end-to-end ownership—spanning extraction, alerting, and automated ingestion—while independently debugging and re-architecting complex Spark pipelines to protect production reliability.

At RD Solutions, I’ve migrated legacy SQL workloads to Delta Lake, fixed production-critical performance and data-quality issues, and automated recurring processes to remove manual intervention. I’ve driven major wins like re-architecting WebAlerts v2 to cut runtime from 22 hours to ~26 minutes (~98% improvement), and improving downstream data quality by eliminating silent type-cast failures. I’m also pursuing DP-700 (Fabric Data Engineer) to keep expanding my platform depth.
