Worked on enhancing the arduino/library-registry by integrating PQCMicro, a C++ library implementing NIST Post-Quantum Cryptography standards for embedded devices such as ESP32, STM32, and Arduino. Focused on improving discovery and onboarding for embedded PQC by adding a dedicated repository link and updating registry metadata to increase traceability and completeness. The technical approach centered on aligning the registry with security roadmaps and business goals, enabling faster and more secure deployments on constrained hardware. Utilized C++ development skills and cryptography expertise to ensure the registry supports production-ready cryptographic solutions, facilitating easier integration for developers working with embedded systems.
