Rockstar🎓
Top SchoolDiana Clarke is a Senior Software Engineer in Edmonton with 15 years of experience building and hardening backend systems in Python, particularly RESTful APIs, benchmarking, and test automation. She’s shipped production integrations (Twilio/Shopify/Shop Pay), saved her employer hundreds of thousands in cloud costs through re-architecture, and created Conbench, a continuous benchmarking framework used by Apache Arrow. A long-time open-source contributor and Python Software Foundation Fellow and past director, Diana has deep contributions to high-profile projects like Apache Arrow, SQLAlchemy, OpenStack Nova and DataFusion, often improving test coverage, benchmark tooling, and Pandas integrations. She blends hands-on engineering with leadership—running teams, chairing PyCon, and improving team processes—while still preferring to write code. Unusually, she pairs computing science with a nursing degree, reflecting a practical, human-centered approach to problem solving. Her work is characterized by a focus on observability, rigorous testing, and measurable performance improvements.
