What I'm looking for

I’m looking for a role where I can build reliable cloud data platforms and warehouse models—owning ETL/ELT, data quality, and performance—while enabling BI and AI-ready analytics with strong stakeholder impact.

I’m a Senior Data Engineer with 5+ years of experience designing, building, and optimizing scalable cloud-based data platforms, ETL/ELT pipelines, and analytics-ready data models. I specialize in AWS and modern data warehouses, with a strong focus on data warehousing, dimensional modeling, data quality, and performance optimization to power business intelligence and AI-driven analytics.

At Systango, I architected 20+ production BigQuery data models processing multi-region marketing data, reducing analyst query time by 40%, and operationalized KPI anomaly detection to improve reporting reliability. I also migrated legacy datasets to AWS using a centralized S3 data lake and built Glue ETL, Lambda-triggered ingestion into Redshift, and orchestrated backfills with Dagster—while translating 10+ dashboards into optimized SQL models to enable faster, AI-ready workflows.
