I’m a Data Engineer with experience building and maintaining data pipelines, ETL processes, and data platforms using Python, PySpark, SQL, Spark, Airflow, and Azure. I enjoy solving data problems, improving pipeline performance, and making data processes reliable and scalable.

What makes me unique is my combination of technical skills and a strong problem-solving mindset. I also enjoy working closely with teams, removing technical obstacles, and helping create well-organized data processes.

I’m looking for a Data Engineer position where I can work mainly with ETL, data pipelines, monitoring, data quality, and data platform improvements, preferably in an international team.
