What I'm looking for

I seek a collaborative, growth-focused data engineering role building scalable, governed data pipelines and enabling analytics/ML teams with automation and quality.

I am a detail-oriented Data Engineer experienced in designing and implementing scalable data pipelines using Python, SQL, PySpark, dbt, and cloud platforms such as GCP and AWS. I focus on ETL/ELT processes, data modeling, orchestration, and data governance to deliver reliable data products.

At Power of Data I built and maintained pipelines with Databricks, Airflow, BigQuery and Dataflow, ensured lineage and access controls, and delivered trusted data products and analytical queries for analytics and data science teams. Previously I created automated ETL pipelines and interactive Power BI dashboards at HupData and managed cross-functional technical projects as a Civil Engineer.

I bring a proactive, collaborative mindset with strong emphasis on automation, quality, and impact, complemented by formal training in cloud data engineering, Spark, Airflow, dbt and Terraform, and active volunteer work empowering women in data science.
