Data Engineer/Data Analytics
Sfera IT
Doświadczenie zawodowe:
I have hands-on experience in data engineering and analytics, starting from building SQL-based ETL processes with SSIS and Python to developing full-scale data pipelines in Azure and AWS. During my early projects, I improved data quality by 30% and reduced query execution time by 25%, while later I engineered Azure pipelines that ingested and transformed open datasets into SQL staging tables and built Power BI dashboards for business insights. Currently, as a Junior Python Data Engineer, I design and optimize AWS Glue pipelines, integrate multiple data sources, and cut query execution time from 1 hour to 10 minutes. I also implemented unit testing (80% coverage), automated dependency management with RenovateBot, created Sumo Logic monitoring dashboards, and improved system reliability and onboarding processes. My experience covers the full data lifecycle — from extraction and transformation to analytics and automation — with a strong focus on performance, quality, and scalability.
