Worked on the cedadev/jasmin-help-hugo-hinode repository to deliver enhanced compliance checking capabilities for the checksit tool, focusing on updated standards and expanded support for European Space Agency Climate Change Initiative files. The approach involved updating documentation and aligning the tool’s compliance logic with current regulatory requirements, thereby improving data interoperability and accelerating processing workflows. All changes were consolidated into a single, well-scoped commit to ensure maintainability and traceability. The work leveraged skills in compliance checking, documentation, and software development, utilizing Markdown for clear communication and documentation alignment throughout the feature update, with an emphasis on regulatory alignment and input format expansion.
