What I'm looking for

I seek a data engineering role focused on cloud ETL, data warehousing, and analytics automation at a data-driven company that values scalable systems and continuous learning.

I am a data engineer focused on designing robust ETL pipelines, data warehouses, and analytics solutions using cloud-native tools. I have built and maintained pipelines with AWS Glue, integrated sources like MongoDB and MySQL, and designed BigQuery schemas to support reliable analytics.

I automate reporting and visualization workflows — for example, developing automation scripts with the Amazon QuickSight SDK to create data sources, datasets, analyses, and dashboards, and loading transformed data into Amazon S3. I also build backend services with Python Flask and have hands-on experience with Redshift, BigQuery, and Spark-based solutions.

My work is driven by a passion for clean data, scalable architectures, and actionable insights; I hold multiple Udacity nanodegrees in data engineering and data analysis and have delivered projects from data modeling to real-time computer-vision prototyping.
