Embedded and Linux-platform software for a next-generation renal-denervation device — from sensor silicon bring-up to a secure, self-healing OS.

• Alpha-1 Embedded Platform

  Led SPI bring-up and system-level debug of the sensor subsystem with hardware and FPGA teams, and built the HAL drivers — temperature sensing, catheter-state integration, EMI test mode, and EEPROM self-tests.

• Aurora OS Reliability

  Built the Linux platform's reliability core: dual-boot with health-gated rollback that refuses to boot an unhealthy image, plus boot validation, health monitoring, and recovery.

  • C++
  • Embedded Linux
  • Yocto
  • Bash

• Secure Build Pipeline

  Integrated cryptographic code-signing into the Aurora OS build pipeline with DevOps, producing signed, verifiable system images.

  • Python
  • GitLab CI/CD
  • JFrog Artifactory

• Containerized App Platform

  Built the infrastructure to package and mount containerized apps inside the OS image, enabling modular deployment and upgrades.

  • Containers
  • Embedded Linux
  • Bash

Developed cross-platform and embedded software for advanced research and development projects.

• AORTA/RIPL

  Designed and implemented a generic filter interface in C++ to allow other researchers to retain, drop, or propagate control/data messages throughout the network while using CTest for unit testing and Kubernetes to build a cluster to run across distributed computing environments.

• STOIC

  Designed and implemented the data visualization libraries used to observe the behavior of our state-of-the-art positioning, navigation, and timing (PNT) algorithms using Python and Matplotlib for real-time experiments as well as post-processing data analysis.

  • Python
  • Matplotlib
