Education
Three semesters of a Bachelor’s degree in Computational Science & Engineering at ETH Zurich; currently pursuing a Bachelor’s degree in Data Science at FHNW.
Areas of focus
Efficient database management with a strong emphasis on sustainable and secure data processing and storage. Design of ETL/ELT processes with a focus on the efficient use of data dictionary information, indexing, partitioning, and the implementation of SCD-secure processes. This ensures minimal CPU usage. Additionally, I have experience in Python, Java, SQL, and C/C++. I am currently further developing my skills in PySpark in combination with object-oriented DBMS solutions.
Why I work for sumIT
“sumIT has been developing and operating self-built data warehouses for many different clients for many years. These systems are still in use today and continue to be expanded, as they were built with sustainability, quality, and scalability — always with the client’s needs at the forefront. I highly value this integrity and way of working, and I will continue to contribute to upholding and advancing these principles.”
