Rockstar🎓
Top SchoolHugh Delaney is a Staff Software Engineer based in Dublin with six years of experience focused on heterogeneous programming, compilers, and GPU backends. He holds an MSc in High Performance Computing (Distinction) and a first-class Mathematics degree from Trinity College Dublin, blending rigorous theory with practical systems work. At Codeplay and now Qualcomm he has delivered production-grade compiler and acceleration solutions, with a particular focus on SYCL, oneAPI and CUDA. Hugh is an active open-source contributor to the LLVM project, where he improved the NVPTX backend—fixing alignment and parameter handling, modernizing tests, and enhancing bfloat/intrinsic support for NVIDIA GPUs. He pairs deep compiler expertise with applied performance engineering and an educator’s patience from years tutoring mathematics. Expect a pragmatic engineer who moves between low-level codegen details and high-level heterogeneous programming models.
