MSc graduate from Toulouse INP - ENSEEIHT (N7), France. I work on hardware/software co-design and low-level performance. I just completed a six-month research internship at INRIA Rennes, where I designed a hardware isolation mechanism for processing-in-memory processors (UPMEM), measured in a cycle-accurate simulator at 5.54% overhead at most, against 26 to 120% for a software scheme, and validated on FPGA. I write about computer architecture, operating systems, networking (RDMA/InfiniBand) and the move from research to industry. I am looking for my first role in systems and performance engineering, AI infrastructure or low-level software. Stack: C/C++, Go, Python, Verilog, Linux, RDMA, Terraform, Ansible.
