Itamar Turner Trauring

PythonSpeed.com is a blog created by Itamar Turner Trauring, a software engineer known for his work on Python performance, memory optimization, and practical tooling for data science and scientific computing. The site focuses on real production challenges: reducing memory usage, making Python code faster, profiling scientific workloads, improving Docker packaging, and understanding how to ship efficient applications. The writing is clear, measurable, and based on hands-on experience rather than theory. Itamar is the creator of Sciagraph, a performance and memory profiler for Python data science, and the author of open source tools such as Fil and Eliot, both designed to help developers understand how their code behaves. His broader mission is to support useful software development, cut CO2 emissions through faster computing, and encourage engineering that matters. Beyond technical work he is active in local bicycle safety advocacy in Cambridge, MA, helping cities adopt sustainable transportation policies. Thanks to this mix of engineering depth and real-world impact, PythonSpeed.com is one of the most practical and thoughtful resources for developers who want to make Python software faster and more efficient.
