Bartosz Paszkiewicz

First-year Computer Science student (20) at Warsaw University of Technology with project-based experience in SQL (query optimization, stored procedures) and Python ETL pipelines. Seeking a summer internship in data engineering to contribute to DWH/cloud migration projects while expanding my skills in Azure and Databricks.

Database System Project (in progress)

• Designed a relational database schema (normalization, PK/FK relationships)
• Developed SQL queries and custom functions (e.g., stored procedures for data validation)
• Optimized query performance (indexing, execution plan analysis)
• Built ETL pipelines in Python (Pandas + SQLAlchemy) for data transformation
• Collaborated via GitLab (version control, code reviews)

Other Programming Projects

• Python applications (basic data structures, simple games and web scraping)
• C++ programs (OOP fundamentals: classes, inheritance)
• Low-level projects in C and Assembly (performance optimization)
