Summary
🤩
Rockstar🎓
Top SchoolEtienne Fortin is an Ingénieur Recherche with 13 years of experience blending experimental particle-physics instrumentation and low-level embedded software for large-scale scientific projects. He has held roles at CERN and CPPM, working on ATLAS liquid-argon calorimetry operations, detector control systems, firmware development and run coordination. Technically fluent in firmware, RTOS and secure trusted execution (OP-TEE, TF-A, EDK2, Zephyr), he contributes to prominent open-source projects that underpin secure boot, trusted environments and STM32 support. His work spans from VHDL for FPGA-based DAQ upgrades to refactoring complex build systems and adding shared-memory APIs for TEE clients, showing both hardware-level and systems-level mastery. Based in Provence-Alpes-Côte d'Azur, he pairs a doctoral background in instrumentation with practical industry experience (STMicroelectronics) and an uncommon habit of shipping production-grade fixes across widely used firmware stacks.

OP-TEE/optee_client
Nov 2016 - Dec 2022
Normal World Client side of the TEE
Role in this project:
Back-end Developer
Back-end DeveloperContributions:281 reviews, 74 commits, 47 PRs in 6 years 1 month
Contributions summary:Etienne primarily contributed to the OP-TEE client, focusing on extending the client API to support shared memory management through file descriptors. This involved implementing new APIs like `TEEC_RegisterSharedMemoryFileDescriptor()`, along with modifications in `tee_client_api.c`, `tee.h`, and `tee_client_api_extensions.h`. Further contributions involved syncing the `tee.h` header with the Linux kernel version, correcting a ULONG_MAX dependency, and refactoring the code by explicitly initializing local variables.

OP-TEE/optee_test
Oct 2016 - Nov 2022
Test suite
Role in this project:Backend Developer & Test Automation Engineer
Backend Developer & Test Automation EngineerContributions:363 reviews, 83 commits, 103 PRs in 6 years 1 month
Contributions summary:Etienne primarily focused on enhancing the test suite for the `optee_test` repository. Their contributions included fixing tests related to deprecated features and memory access rights, specifically addressing issues with the CFG_ENC_FS configuration. They introduced new tests for Secure Data Path (SDP) functionality, encompassing buffer allocation, data injection, transformation, and verification. Furthermore, the user refactored the build process, particularly "make clean," to remove build artifacts and prevent potential errors.
