Worked on foundational documentation and system design for the Test Node Orchestrator within the embedded-purdue/slayterHIL repository, focusing on improving onboarding and integration processes. Developed detailed architectural documentation outlining the use of protobuf for data serialization and conducted a technical evaluation of SPI, USB, and UART as physical-layer options, ultimately selecting SPI for orchestrator communication. Enhanced team onboarding by updating setup instructions and clarifying directory structures, which streamlined the initial setup for new contributors. Leveraged skills in embedded systems, documentation, and system design, using Markdown to ensure clarity and consistency. These efforts established a stable base for future development and testing.
