Summary
🤩
Rockstar🎓
Top SchoolJack Mazanec is a software engineer based in Boston with a decade of experience building low-level systems and performance-sensitive infrastructure. Currently at AWS, he focuses on kernel-level work, SIMD-optimized algorithms, and cross-platform build/deployment for large open-source projects like OpenSearch and NMSLIB. His open-source contributions include non-blocking keyboard input and system-call changes in an educational OS kernel and SIMD-accelerated similarity functions that improve k-NN performance. A Notre Dame computer science alum and former TA for operating systems and computer architecture, he pairs hands-on systems coding with teaching experience that sharpens his ability to explain complex concepts. Practical and curious, he often demonstrates work end-to-end (for example shipping a snake game to validate kernel changes) and has a track record of making low-level changes that matter at scale.
