Summary
🤩
Rockstar🎓
Top SchoolOrson Peters is a software engineer based in Leiden with 13 years of hands-on experience building high-performance systems and developer tooling. He combines a strong academic background (MSc cum laude in Computer Science) and research experience as a PhD candidate with practical engineering at Polars, contributing to a multithreaded, vectorized dataframe engine in Rust. His open-source work spans low-level algorithmic improvements (pattern-defeating quicksort), safe and efficient data structures (slot map implementations), and cryptographic C libraries (Ed25519), showing fluency across languages and performance-focused domains. Orson also contributes to build systems and image codecs, demonstrating attention to reproducible builds and tooling. Notably, he removes floating-point dependencies and hardens unsafe APIs, revealing a preference for robust, portable code rather than quick patches. He brings an analytical, performance-first mindset that bridges research rigor and production-grade engineering.
