Rockstar🎓
Top SchoolKrzysztof Jordan is a senior software engineer with 13 years of experience building large-scale backend and ML-infused infrastructure in the San Francisco Bay Area, currently at Apple after a multi-year tenure at Meta. He has driven measurable impact on global products—reducing language restart times by 78%, cutting backend CPU use by over 80%, and enabling precise language targeting for tens of millions of users. His work spans PyTorch preprocessing, migration of legacy pipelines to Spark/Presto, and scalable logging and metric systems that radically lowered operational costs. Comfortable leading cross-functional initiatives, he focuses on modernizing technical debt while improving developer experience and on-call efficiency. With an academic foundation in computer science and mathematics and early hands-on mobile and systems development, he blends low-level engineering rigor with production ML and large-scale data engineering.
