Worked on the mcneel/developer.rhino3d.com repository to clarify and codify requirements for core-hour billing, specifically establishing that no licenses are required for compatibility. Addressed ambiguity in licensing constraints by updating documentation and technical specifications using Markdown, ensuring alignment across product, compliance, and engineering teams. The approach focused on requirements engineering and disciplined version control, with changes captured in a dedicated commit. This documentation update streamlines compliance checks and accelerates onboarding for future billing-related features. The work demonstrates a methodical process in technical writing and documentation, directly reducing business risk and improving time-to-market for billing system enhancements.
