Seattle, Washington, United States
Summary
🤩
Rockstar🎓
Top SchoolGaurav Aggarwal is a software development engineer based in Seattle with eight years of experience building and porting embedded and IoT systems, primarily at Amazon Web Services. He has deep low-level expertise in real-time OS kernels and hardware bring-up, contributing ports and architecture-specific fixes to FreeRTOS (including Cortex-A53 and RISC-V) and Amazon FreeRTOS. His work spans secure device connectivity—adding Device Defender demos and PKCS11 improvements to the AWS IoT embedded C SDK—and TLS error-handling improvements in mbedtls for resource-constrained environments. Comfortable in both assembly and C, he focuses on making platform integrations reliable and CI-friendly, often surfacing non-obvious test and build fixes that improve long-term maintainability. Trained at Cornell (MS CS) and with prior experience at Adobe and in analytics, he blends academic rigor with practical production engineering.
