Grenoble, Auvergne-Rhône-Alpes, France
Summary
👤
Senior🎓
Top SchoolJean-luc Pons is a senior software engineer with 15+ years building high-performance scientific and accelerator-control software at the European Synchrotron (ESRF). He designs and leads projects spanning RF control, beam dynamics, vacuum simulation and digital twins, publishing work on GPU-based Monte Carlo and real-time orbit correction systems. A lifelong programmer who started on an Amstrad at 12, he combines deep applied-math training with hands-on CUDA and cryptographic engineering. His open-source projects include VanitySearch and Kangaroo, the latter achieving a 2020 world record by using 256 GPUs to solve an ECDLP instance with 114 unknown bits. Comfortable shipping low-level CUDA kernels and large control-system stacks alike, he brings rare cross-disciplinary expertise at the intersection of scientific instrumentation, parallel computing and cryptography. Based in Grenoble, he pairs academic rigor with pragmatic system delivery in production scientific facilities.

Pollard's kangaroo for SECPK1
Role in this project:
Back-end Developer
Back-end DeveloperContributions:17 releases, 197 commits, 204 pushes in 4 months
Contributions summary:Jean-luc implemented GPU support for Pollard's Kangaroo algorithm, a method for solving the elliptic-curve discrete logarithm problem. This involved writing CUDA code within the `GPUEngine.cu` file, suggesting a focus on parallelizing the algorithm for GPU execution. The user also added CUDA-related files and made modifications to the `Kangaroo.cpp` and `SECP256K1.cpp` files, integrating the GPU implementation into the broader project structure.
