What I'm looking for

I’m looking to lead end-to-end data engineering—lakehouse/warehouse pipelines, data governance, and batch/stream processing—within a team that values code quality, documentation, and mentoring, delivering measurable business impact like cost reduction and compliance.

I’m a Senior Data Engineer with extensive experience delivering world-class data solutions across multiple countries. I focus on building production-grade data pipelines that combine governance, integrity, and strong delivery practices.

In my most recent role, I was the first Senior Data Engineer hire at EvolutionOne, designing and implementing a new organization data system architecture in Microsoft Fabric using Medallion Architecture. I set up Data Lakehouse and Data Warehouse layers (bronze to silver to gold), leading a team of 2 Junior Data Engineers while optimizing and reducing data team operation costs by 60% through Fabric migration and capacity/SKU tuning.

Previously at Microsoft, I helped drive EU and GDPR compliance for 45% of BAP products through global ETL/ELT pipelines and HLL algorithm implementation. I also contributed to setting up the Microsoft BAP GIA Internal Data Warehouse and Data Lakehouse and onboarded 100% of BAP data products to 90%+ SKU coverage using data modeling and ingestion pipelines.

I’ve also delivered successful migrations and analytics platforms, including moving UCARD data layers from AWS to Digital Ocean and migrating POS services from MySQL to Postgres to reduce downtime by 50%. From lakehouse builds to knowledge graphs using Neo4j and Cypher, I bring a practical engineering mindset—documentation, testing, mentoring, and collaboration—so teams can ship reliable data assets.
