Torrance, California, Us

- Developed flight software architecture and components in C++ for cubesat-class avionics running FreeRTOS on STM32 MCUs.- Developed and organized the flight software architecture and create a work breakdown.- Wrote and established a Software Development Process to support writing high-quality quality software and satisfy requirements for FAA re-entry license.

Long Beach, California, Us

- Designed, developed, debugged and integrated FreeRTOS based CubeSat flight software from scratch on an aggressive schedule including:- - The central system API to share data between software components in the system and expose data for telemetering and telecommand. The component’s design accounts for the constrained memory environment, allows for reliable real-time performance, loose coupling between software components, and clear naming of data points for user interpretation for both flight and ground software development.- - A suite of base classes for flight software components to standardize and abstract the creation of tasks, telemetering of task status, and provide for synchronized task scheduling in the system.- Led five person software team developing the flight and ground software. - Created software development and review process and mentored the team in its implementation.- Led the adoption of ticketing software for tracking and documenting open work on hardware in the loop tables, flight hardware, and flight and ground software.- Led ESD and clean room controls implementation and awareness training for the company.

Hawthorne, California, Us

- Exercised leadership across functions as a responsible engineer from the flight software department for the bring-up of a new Dragon 2 HITL table to ensure work by other departments was continuing on schedule to meet Dragon Flight Software’s needs.- Responsible engineer for performing CRS-22 run for record testing of Dragon 2 flight software and releasing software for flight.- Performed data review of Dragon 2 hardware in the loop (HITL) test results to identify and diagnose problems with the testbeds or with the flight software in support of the Crew-2 and CRS-22 missions for NASA.

Arlington, Va, Us

- Hardware in the loop (HWIL) software lead for a rapid-paced DARPA development effort. Responsibilities include managing scope of work, making architectural decisions to ensure work products are aligned with program schedule and user needs, participating in peer reviews, and C++ software development.- Led update effort for a legacy HWIL station. Developed new design, redlined new cabling, and updated legacy C code to run on new RedHat 7 systems with Raytheon’s latest C++ device abstraction classes. Led weekly standup to manage cybersecurity, IT, and procurement’s support of the project.- Debugged Linux PCI FPGA card driver to quantify erroneous behavior in the driver and the FPGA’s firmware and identified root causes.- Co-led the integration and acceptance testing of an HWIL station, prepared and led acceptance test review meeting with management, and tracked findings closure.- Developed and integrated C++ classes connecting digital simulation models to the HWIL interfaces.- Configured, tuned, and debugged RedHat Linux installations to achieve real-time performance.-Developed real-time C++ software to connect 6DOF simulations with tactical hardware for hardware in the loop (HWIL) testing. Experience with Linux, PCIe buses and drivers, object-oriented programming, serial/UART, SDLC, and MIL-STD-1553.

- Performed formal verification of the Boeing CST-100 Starliner flight software in a dynamic environment with an aggressive schedule.- Commended by both Requirements and IV&V for thoroughness and quality of test designs.- Verified the fault detection, isolation, and recovery (FIDR) requirements for the multi-fault-tolerant avionics communication buses and portions of the FDIR requirements for the integrated propulsion controllers.- Identified undesired fault responses resulting from the complex interaction of multiple requirements and worked with the requirements and flight software engineers to develop corrected requirements and software.- Developed improvements to test framework and new shell scripts to improve efficiency and productivity of developing and running test scripts.
