As a Principal Software Development Engineer at Mastercard, I bring over two decades of expertise in cryptographic security and distributed systems in the payment processing business. My focus is on delivering secure, scalable solutions leveraging cutting-edge technologies like Trusted Execution Environments (TEE), Hardware Security Modules (HSM), and high-performance cryptographic services for global infrastructures. With deep technical leadership, I empower development teams to adopt robust practices in languages like Rust, Java, and C++ to elevate Mastercard\'s security capabilities. By blending my passion for cryptography with cloud innovation, I lead advancements in certificate management, confidential computing, payment processing, and system automation. My mission is to enhance Mastercard\'s resilience against emerging security threats while optimizing operational efficiency across AWS, Azure, and on-prem environments. Collaborating with global teams, I aim to drive transformative outcomes in payment security and trusted infrastructures.
