What I'm looking for

I’m looking for a Senior Data Engineer role where I can build cloud-native data platforms, own scalable ETL/ELT and streaming pipelines, and drive observability, cost optimization, and automated testing that help teams move faster.

I’m a data engineer with 7 years building cloud-native data platforms and analytics solutions across energy and software, focused on scalable pipelines, measurable performance, and trustworthy data. I’ve used Python, SQL, ETL/ELT, Airflow, dbt, Spark, and Kafka to reduce ETL latency, improve data quality, and enable self-serve analytics.

Most recently, I designed a GCP data lake with BigQuery, Cloud Storage, and Dataflow (reducing query time by 60%) and delivered near-real-time order processing with Kafka and Dataflow (cutting order-to-visibility latency from minutes to seconds). I also optimized BigQuery costs by 30% and brought observability with Prometheus and Grafana to improve incident response times by 45%, while mentoring engineers and building CI/CD for safer dbt and Airflow deployments.
