Summary
🤩
Rockstar🎓
Top SchoolRuchika Gupta is a Sr. Principal Engineer with over 16 years of deep expertise in embedded systems, secure firmware, bootloaders (U-Boot/TF-A), and processor architecture for ARM and PowerPC platforms. She has architected secure platform features including Secure Boot, ARM TrustZone-based secure firmware, device lifecycle management, and a software HSM/TPM emulator, and holds a patent-pursuing methodology for device identity and cloud enrollment. At NXP and previously Linaro she combined hands-on low-level development with security architecture work, contributing to OP-TEE and PKCS#11 implementations and test suites to harden TEE cryptography and key management. Her open-source contributions to OP-TEE include enabling boot/security features (GICv3, Pointer Authentication, Xen integration) and strengthening PKCS#11 support and cryptographic tests, demonstrating impact on both build and trusted-side code. Comfortable in C, assembly and kernel/driver work, she pairs rigorous academic grounding (BITS, top grades) with practical board bring-up and multicore firmware design experience. Notably, beyond product deliverables she has driven customer anti-cloning solutions and lightweight firmware primitives for multicore reference platforms.
