Summary
👤
Senior🎓
Top SchoolAlexandre Gonzalo is a Principal Software Engineer with two decades of deep expertise in embedded security and a specialty in ARM platforms from ARM7TDMI to ARMv9. He has led core development and architecture teams across payment, mobile, and automotive domains, delivering Trusted Execution Environment (TEE) solutions, applied cryptography, and high-performance secure firmware. At Trustonic and now Arm, he combined hands-on C/Rust development with system architecture, validation, and project leadership to ship production-grade security stacks and APIs. Alexandre contributes to notable open-source work such as OpenSC, adding PKCS#11 mechanisms and SHA3 support, reflecting a practical commitment to interoperable cryptographic tooling. He balances low-level optimization (bare metal, boot loaders, μkernels) with modern platform integrations (Linux/Android key services and Remote Provisioning). Based in the Greater Nice area, he’s known for mentoring teams and translating complex cryptographic requirements into auditable, efficient implementations.

Contributions summary:Alexandre primarily focused on enhancing the security and functionality of the `pkcs11-tool` within the OpenSC project. Their contributions involved implementing support for new cryptographic mechanisms, specifically CKM_RSA_PKCS_OAEP and CKM_RSA_X_509, and also addressing build issues related to OpenSSL configurations. Further improvements included the addition of SHA3 algorithms for encryption and decryption and the addition of support for the OpenSsl signature format. They also debugged and improved existing code, fixing a signature verification bug and improving code formatting.
