What I'm looking for

I seek roles where I can design scalable cloud-native ETL and data warehouses, drive performance optimizations, and collaborate with analytics teams to deliver actionable insights while growing in cloud and data architecture responsibilities.

I am a data engineer with over 4 years of experience building scalable ETL pipelines and data warehouses across AWS and GCP. I focus on designing cloud-native, serverless pipelines that improve data availability and reduce operational cost.

At my current role I led a migration from AWS to GCP that cut cloud costs by 20% and developed 50+ ETL pipelines using Cloud Run, Pub/Sub, Dataproc, and BigQuery, improving data availability by 40%.

I optimize performance through Apache Spark, SQL tuning and workflow orchestration with Airflow, achieving query and pipeline execution improvements of about 40% and boosting BI data quality by 30%.

I pair technical execution with business alignment—designing data warehouse models, building analytics solutions and delivering insights that drive outcomes like a 22% increase in customer retention and faster stakeholder decision-making.
