Summary
🤩
Rockstar🎓
Top SchoolIrit Katriel is a deep learning compilers engineer and long‑time CPython core developer with 14 years of experience spanning research, finance, and platform engineering. She has driven Python performance and correctness at scale—contributing to core bytecode, exception handling (notably PEP 654), and developer documentation that reorganized CPython’s internal guides. Her career blends academic rigor (PhD and postdoc work in algorithms and combinatorial optimisation) with practical systems delivery at Microsoft, Bank of America, and now NVIDIA. She led technical efforts such as the Quartz dependency graph and performance tuning for compilers and interpreters, and is comfortable moving between low‑level VM internals and high‑level language design. A less obvious facet is her early background in microprocessor simulation and even writing a children’s science column, reflecting a mix of deep technical curiosity and clear communication. Based in London, she combines research pedigree with hands‑on engineering to improve language runtimes and ML compiler stacks.
