Top School

Clément Chigot is a software engineer with nine years of experience specializing in low-level toolchain and embedded systems work, currently porting GCC and maintaining binutils and QEMU at AdaCore. He has deep expertise in porting and hardening compilers and runtime for niche platforms—especially AIX and embedded OSes like QNX and LynxOS—and has contributed fixes to the core Go language to improve AIX support. At Atos he led teams integrating and packaging open-source toolchains, automating RPM delivery with Jenkins and standardizing build processes across VMs. His background in physics, electronics and embedded software gives him a pragmatic systems-level view that bridges compiler internals, OS constraints and release engineering. A long-term open-source contributor, he combines hands-on C/Go toolchain work with operational discipline for reproducible builds and platform portability.
