What I'm looking for

I’m looking for a role where I can build and maintain scalable ETL/ELT data pipelines and platforms, strengthen data quality with monitoring and validation, and optimize analytics performance using Airflow, Spark, dbt, and SQL.

I’m a Data Engineer with 5+ years of experience building and supporting data pipelines and data platforms. I focus on reliable data processing and data quality across the full ETL/ELT lifecycle.

I’ve worked extensively with Python, Apache Airflow, Apache Spark, dbt, and SQL to orchestrate pipelines, build data integration workflows, and improve analytics infrastructure. In practice, I’ve developed DAGs, optimized SQL and data-processing workflows, loaded data from Kafka into data lakes, and engineered systems to prepare data for ML pipelines.

I also bring strong platform and operational support skills—creating reusable templates for more reliable DAG development, implementing CI/CD processes, and using monitoring and validation for data quality. I’m energized by scalable architecture, performance improvements, and turning complex data flows into dependable outcomes.
