Summary
👤
Senior🎓
Top SchoolKealan Mccusker is a Chief Cryptographer with 13 years of experience translating advanced cryptographic research into production-grade, deployable systems for digital asset custody and authentication. Trained as an electronic engineer and PhD in cryptography, he began in ASIC/FPGA and embedded systems, which gives him a systems-level view he applies to distributed cryptography, trusted execution, and cloud-native infrastructure. He has led teams building MPC-based threshold signature platforms, integrating TEEs like AWS Nitro Enclaves and running production deployments on Kubernetes with Terraform. His work spans cryptographic libraries, authentication protocols (MPIN), and large-scale distributed systems—balancing protocol rigor with operational resilience and threat modelling. Known for turning academic primitives into auditable, real-world custody workflows, he mentors multidisciplinary teams to deliver secure-by-construction solutions. Based in Dublin, he combines hardware-rooted intuition with a decade of applied cryptography in high-assurance, production environments.
