Summary
👤
Senior🎓
Top SchoolRubén Díaz is a Senior Software Developer with six years of hands‑on experience building high‑performance, cross‑domain systems spanning C++, firmware, Linux drivers and FPGA acceleration. He combines production delivery at Worldline—modernizing large C++ codebases, introducing C++20 idioms, CI/CD and a Nix‑based containerized dev environment used by ~400 engineers—with deep research experience at the Barcelona Supercomputing Center integrating CUDA, OpenCL and RISC‑V into task‑based runtimes. Rubén excels at performance debugging, trace/profiling work and bridging hardware/software boundaries (bootloaders, DMA, PCIe, Ethernet drivers and HBM integration). He’s an active mentor and technical communicator who builds developer tooling and cloud IDEs to improve DX, and is fluent in English and Spanish. A not‑so‑obvious strength is his blend of low‑level FPGA/RISC‑V systems work with pragmatic developer experience improvements that scale across large teams.
