Summary
🤩
Rockstar🎓
Top SchoolMazen Kharbutli is a Senior Software Engineer and performance architect with a 12+ year track record building mission-critical systems at Google, Apple, AWS, Meta and now OLIX, combining deep systems engineering with hands-on leadership as a Team/Tech Lead for over a decade. He holds a PhD in Computer Engineering and has 20+ published papers with 1,100+ citations, reflecting a rare blend of academic rigor and production-grade impact. Mazen has driven CPU/system software and SOC architecture work, and his practical performance optimizations span from dynamic instrumentation—contributing to DynamoRIO’s DRCacheSim cache simulator—to AI and systems co-design. Colleagues rely on him to translate microarchitectural insight into measurable system gains, and he frequently bridges research ideas into shipping products. Based in Austin, he brings both a scientist’s curiosity and an engineer’s pragmatism to complex performance problems across cloud and device platforms.

Contributions summary:Mazen primarily contributed to the DRCacheSim tool, focusing on improving its cache simulation capabilities. They added support for inclusive caches and cache line invalidation, implemented a cache hierarchy configuration file reader/parser, and integrated it with the simulator. The user also worked on disabling the writing of misses triggered by hardware prefetches and fixed various test-related issues. Furthermore, the user added a basic last-level cache (LLC) miss analyzer and the interface for it.
