What I'm looking for

I’m looking for a Data Engineering role where I can build scalable Azure Databricks/Delta Lake pipelines, own ETL/ELT and migration work, and collaborate with international teams to improve data reliability and cost efficiency.

I’m a Data Engineer with 5+ years of experience in Azure Databricks, SQL, and ETL/ELT across banking and consumer goods data environments. I build scalable pipelines that support executive reporting and mission-critical migration work.

In my current role, I’ve built end-to-end pipelines in Azure Databricks and SQL to support campaign analytics for Reckitt. I use Delta Lake features like time travel, optimize, and vacuum to improve reliability and support storage cost reduction, and I integrate Databricks workflows with Azure Data Factory for streamlined ingestion and transformation.

Earlier, I led a core banking data migration at Banco Pichincha, moving SQL Server 2009 to 2019 with zero data loss while preserving regulatory compliance. I also designed validation models and integrity queries to guarantee post-migration consistency, and I’ve supported backend performance through stored procedures, views, functions, triggers, and ETL processes.
