PROFILE
David Harris
David Harris developed foundational requirements management, configuration, and documentation systems for the nasa/nos3 repository, enabling reliable simulation and mission software readiness. He established a doorstop-based framework for traceable requirements, formalized simulation and software specifications, and overhauled mission configuration using YAML and XML. His work included integrating Arducam sensor support with F' tooling, updating deployment guides for Docker-based environments, and aligning submodules to reduce integration risk. Through detailed technical writing and documentation improvements, David streamlined onboarding, clarified fault scenario procedures, and enhanced maintainability. His contributions demonstrated depth in configuration management, requirements engineering, and system administration, delivering robust, reproducible workflows.
