Top School

Yee Lim is a software engineer based in Mannheim, Germany with nine years of experience building data-centric, performance-sensitive systems, recently focusing on Clojure and back-end database engineering. They combine strong data-science instincts with practical engineering—having implemented high-accuracy bioinformatics classifiers and a string-matching correction that cut error rates from ~40% to single digits. Yee has contributed performance and correctness fixes to Datahike, an immutable distributed Datalog engine, demonstrating expertise in query optimization, indexing, and database migrations. Comfortable across Python’s data ecosystem as well as lower-level languages like C and Java, they bridge algorithmic rigor with production-grade engineering. Their track record spans industry and research, from CNN pipelines for 3D inference to enterprise middleware and cloud deployment automation. Colleagues can expect a pragmatic problem-solver who prefers measurable improvements in performance and data quality.
