PROFILE

Helena Bermúdez Sabel

Worked on the TEIC/TEI repository over three months, focusing on XML schema development, documentation, and data modeling. Improved Relax NG schema documentation by correcting minOccurs and maxOccurs annotations, ensuring accuracy for downstream tooling without altering schema functionality. Managed change control by reverting unintended commits to maintain generated file integrity. Finalized the stable TEI 4.10.0 release by updating versioning and aligning with release governance, minimizing risk for consumers. Addressed a critical bug by correcting attribute handling from @type to @rend, enhancing data integrity and rendering accuracy. Demonstrated expertise in XML processing, schema validation, and precise, low-risk change management.
