What I'm looking for

I'm seeking remote or hybrid Data Engineering roles.

In my independent data engineering portfolio, I built an e-commerce data lake that ingests DummyJSON API data into MinIO and organizes it across RAW, ODS, and Data Mart layers. I used idempotent Airflow DAGs and SQL transformations to support repeatable ingestion and BI dashboards.

For my SpaceX analytical pipeline, I processed API data through PostgreSQL and seven dbt-core models into ClickHouse. I added 16 automated dbt tests and configured the pipeline to halt on failure.

I also built a Spark ETL pipeline for roughly 3 million NYC Yellow Taxi records, orchestrated with Airflow on a containerized Spark/HDFS cluster. It included automated data quality checks, Telegram failure alerts, and SQL analytics through Trino and Hive Metastore.
