Manchester, England, United Kingdom
Summary
🤩
Rockstar🎓
Top SchoolAsher Dobrescu is a software engineer based in Manchester with seven years’ experience focused on compiler engineering and performance on AArch64 targets. Now at Arm—where he progressed from intern to graduate engineer and now a full engineer—he has contributed to LLVM, improving the MCA tool and AArch64 scheduling models to prevent dependency bugs and add flag-setting semantics. His background in computer science and mathematics from the University of Manchester pairs strong theoretical grounding with hands-on work translating NEON kernels to SVE and adding OpenMP Fortran support. Colleagues know him for spotting subtle target-specific correctness issues and for mentoring juniors during placement projects, reflecting both technical depth and collaborative instincts.
