What I'm looking for

I’m looking for a remote-first, cloud-native environment where I can build ETL/ELT pipelines, enforce security/compliance, and deliver measurable uptime and data quality improvements with Git-based CI/CD and Agile execution.

I’m a result-oriented Data Engineer with a foundation in high-stakes IT Executive leadership. I architect scalable data pipelines and maintain 99.9% system uptime for global-scale events, bridging complex data infrastructure with business intelligence goals.

In my current role, I design automated, fault-tolerant ETL/ELT workflows using Python and SQL, transforming raw data into analytics-ready datasets for business intelligence. I lead cloud migration to Snowflake/BigQuery, improving query performance by 35% while reducing overhead costs, and I implement automated data validation to sustain 99.9% data integrity and cut manual reconciliation time.

I also bring strong infrastructure and security leadership, enforcing global security and compliance standards like GDPR/SOC2. From FIFA World Cup operations to healthcare emergency response work, I’ve managed real-time data streams, zero-downtime peak loads, and rigorous encryption/privacy requirements—then operationalized it all through remote-first collaboration with Git/GitHub, Docker, and Agile CI/CD.
