Summary
👤
Senior🎓
Top SchoolJoel Bueno is an operating systems, security, and firmware engineer with eight years of hands-on experience building low-level software across RISC-V, ARM, x86, MIPS and RISC-V platforms. He specializes in assembly, C/C++ and Rust, and has shipped firmware, boot firmware (BootROM/UEFI/Coreboot/OpenSBI), kernel drivers and full-system QEMU emulation models that enabled multi-chiplet, NUMA and SMP prototypes to be tested end-to-end. Joel blends HW–SW co-design—debugging RTL, prototyping accelerators, and diagnosing timing-sensitive faults—with production-focused practices like CI/CD and secure boot flows. He has contributed to Coreboot, Spike and QEMU upstream and written Rust Linux drivers for secure, high-performance inter-processor communication. Comfortable running projects and mentoring interns, he pairs deep architectural curiosity with a practical, methodical approach that prioritizes correctness and performance. Based in Reus, Catalonia, he’s as likely to be reading obscure architecture manuals as he is to architect repeatable emulation infrastructure for commercial products.
