Senior Data Engineer and Data Architect delivering compliant, automated lakehouse platforms.
MexicoWhat I'm looking for
I’m a Senior Systems Engineer and Data Architect with 10+ years designing and operating cloud data ecosystems across Azure and AWS. I specialize in Lakehouse and Data Mesh architectures, complex ELT/ETL automation, and translating regulatory and business requirements into production-grade data infrastructure.
In my most recent role, I built a fuzzy-matching metadata framework in Dataiku and Teradata to unify disconnected sources without predefined relationships, then led a zero-downtime migration to Azure Databricks—refactoring legacy SQL stored procedures into optimized, distributed PySpark and Delta Lake pipelines. I’ve delivered measurable impact by protecting $10M USD in annual revenue, reducing processing cycles by 95%, and sustaining 99.9% data veracity in compliance-critical environments.
