Summary
🤩
Rockstar🎓
Top SchoolKoutheir Attouchi is a Software Design & Development Engineer with 13 years of experience specializing in embedded systems, virtual machines, operating systems and compilers, using Assembly, C++ and Rust. He has a rare track record of porting Oracle Java SE and GraalVM native-image to niche targets like Windows CE/ARMv7-A and QNX/ARM, demonstrating deep low-level and cross-platform expertise. A PhD-trained engineer, he combines academic rigor with hands-on systems work—authoring scientific articles and contributing substantive fixes to projects such as GraalVM and the Capstone disassembly framework. His open-source contributions span build systems, platform compatibility patches and binary analysis tooling (e.g., PE/COFF support in bingrep), reflecting a pragmatic approach to portability and tooling. Curious, frank and collaborative by nature, he migrated his pet projects to Rust since 2016 and applies that modern-systems mindset to challenging legacy platforms. Based in Old Toronto, he thrives on bridging compiler/runtime theory with production ports and build engineering.
