Summary
👤
Senior🎓
Top SchoolPascal Pfeil is an applied scientist and software engineer with 10 years of experience focused on databases, currently working on AWS Redshift in Munich. He has a strong track record of shipping database features and performance improvements—ranging from adding new Redshift data types and instance optimization to enabling 50x faster subquery performance at Snowflake. His background blends industrial internships at Google, Oracle, and Siemens with research stints at MIT on instance-optimized indexing, reflecting a habit of turning research insights into production systems. Pascal’s work often targets low-level storage, query optimization and scalability, and he has repeatedly delivered measurable improvements to partner return rates and query throughput. He holds advanced software engineering training from top German universities and brings a pragmatic, research-informed approach to building high-performance data systems. A less obvious strength is his early experience in system administration and high-throughput REST services, which gives him end-to-end operational insight into database deployments.
