Hi, I'm Bartlomiej Sus, a Senior Data Engineer specializing in data warehousing and ETL optimization. Over the past 20 years, I have improved SQL/ETL performance, led successful data migrations, and built scalable data platforms across fintech, healthcare, and logistics. I love turning complex data into actionable insights using Snowflake, AWS, Python, Spark, Airflow, and DBT. I'm open to UK/EU remote or hybrid roles and am comfortable with B2B arrangements outside IR35. I have hands-on experience across data/big data, data warehouse, ETL/ELT, and migrations, with a strong focus on SQL, Snowflake, AWS, Airflow, Python, Spark, and data vaulting. I’m energized by building robust data architectures and delivering value through data-driven decisions in fintech, healthcare, and enterprise environments.…Hi, I'm Bartlomiej Sus, a Senior Data Engineer specializing in data warehousing and ETL optimization.
