What I'm looking for

I want to keep building scalable, governed data platforms that modernize legacy systems and deliver trusted BI—using end-to-end pipelines, strong CI/CD, and clear visualization—so technology directly supports business strategy and measurable impact.

I’m a Data Engineer with extensive experience managing complex Big Data and Business Intelligence projects, developing end-to-end solutions from data extraction and transformation to interactive dashboards that drive strategic decision-making. I focus on building robust data pipelines that ensure performance and scalability, even when migrating from fragmented, legacy codebases.

Most recently, I work as a Senior Data Engineer on a data modernization initiative, collaborating with Architecture, Engineering, and Business teams to migrate from Oracle Cloud Infrastructure (OCI) to Microsoft Fabric. I proposed and led a Medallion Architecture across Azure Blob Storage and Fabric Lakehouses/Warehouse, and I translate trusted QlikView/Qlik Sense metrics into Power BI Semantic Models and DAX measures to establish a governed migration baseline.

Across roles in customer loyalty and large-scale ingestion/processing, I’ve built batch and streaming pipelines using Azure services, Spark, and Kubernetes, while applying agile methodologies like Kanban and Scrum. I also bring strong DevOps and orchestration practices with Jenkins and Airflow, and I deliver BI value through Power BI, QlikView, Qlik Sense, SSRS, and SSAS-driven tabular models—turning complex datasets into actionable insights.
