Lead Embedded Systems Engineer with hands-on experience delivering secure, crypto-oriented embedded products from concept to market. As the primary engineer behind the PSG1 device, I led the design and implementation of its complete firmware and security architecture — building the foundation for trusted key management, cryptographic operations, and device integrity throughout the product lifecycle. I specialize in low-level C/C++ development, secure hardware integration, and trusted execution environments, building systems that embed cryptographic primitives, Secure Elements, and Trusted Applications for uncompromising protection. My expertise spans firmware security, hardware-software co-design, and the implementation of resilient, production-ready codebases that prioritize both performance and integrity. Driven by precision and purpose, I combine deep technical execution with ownership and collaboration — delivering secure, scalable, and reliable systems that stand at the intersection of embedded engineering and real-world product impact.
