Rockstar🎓
Top SchoolAndi Zimmerer is a doctoral researcher and seasoned backend engineer with a decade of experience building high-performance data systems, most recently focused on databases at UTN's DATA Lab. Previously at Snowflake he worked on selective query acceleration in the Search & Pruning team, and he contributed substantive features to the TiKV project, improving vectorized string functions and coprocessor plugins for a widely used distributed transactional key-value store. He combines strong academic pedigree (M.Sc. programs at TUM and collaborations with MIT CSAIL) with practical product experience from startup founding to enterprise engineering. Andi also co-designed and taught a master's Data Engineering course, bringing research-backed teaching methods to curriculum development. Based in Berlin, he blends low-level systems optimization with applied research, and has a knack for turning complex query and storage problems into pragmatic, production-ready solutions.
