I am a doctoral researcher at the Data Systems Lab at the University of Technology Nuremberg (UTN) working with Prof. Andreas Kipf. My interests lie in optimizing database storage, secondary index structures for data pruning, and high-performance systems programming.

Before that, I worked for three years at Snowflake Inc. as a database software engineer on search optimization, optimizing top-k queries [1][2], and data pruning.

I earned my M.Sc. with honors as part of the Software Engineering Elite Graduate Program from the Technical University of Munich (TUM), the University of Augsburg, and the Ludwig Maximilian University of Munich (LMU) where I specialized in data processing systems. My thesis on automated data partitioning for dynamic analytical workloads was written at MIT’s Data Systems Group under the supervision of Prof. Tim Kraska.
