Summary
🤩
Rockstar🎓
Top SchoolJakub Chlanda is a seasoned compiler engineer with 15 years’ experience specializing in heterogeneous runtimes and code generation for CPU, GPU, DSP and FPGA targets. Currently leading compiler work at Access Softek after a long tenure at Codeplay, he has deep practical knowledge of LLVM internals and GPU offloading, demonstrated by contributions to the llvm-project fixing CUDA and AMDGPU backend issues. Based in Edinburgh, he combines systems-level rigor with a knack for diving into “dark corners” of toolchains to improve correctness and performance. An MEng-trained engineer with an unusual background in forest management lore, he blends methodical engineering discipline with curiosity that drives cross-target portability and low-level optimization.
