Sarah McCarthy contributed to the TYPO3-Documentation/TYPO3CMS-Reference-CoreApi repository, focusing on extensibility and documentation for TYPO3’s backend and API. She engineered PSR-14 event-driven features to enable customizable form handling, backend user management, and dynamic content previews, using PHP and JSON to implement robust extension points without core modifications. Her work included overhauling Composer migration guides, clarifying extension metadata, and improving deployment documentation, which streamlined onboarding and reduced integration risks. By updating localization mechanisms and aligning documentation with evolving core functionality, Sarah ensured maintainable, clear, and future-ready references, demonstrating depth in backend development, technical writing, and configuration management.
February 2026 (2026-02): Delivered the Inline Language Domain Localization for TYPO3 in TYPO3CMS-Reference-CoreApi. Introduced a new method to load labels directly from language domains, preserving backward compatibility to ensure smooth migration. Extended localization support to JavaScript via the inline domain mechanism. Updated relevant API and backend documentation and incorporated code-review feedback. This work enhances localization maturity and streamlines multilingual site integration, with changes prepared for the main release.

January 2026 – TYPO3CMS-Reference-CoreApi: Two PSR-14 event-based features delivered to enhance extensibility and content preview workflows. Key deliverables: - Backend user management extensibility with PSR-14 events: added event classes and documentation to enable modification of backend user groups and file mounts (commit d8ede8ddb437807e0567532642f730b1f07ed623). - Dynamic backend content previews via PSR-14 events: introduced an event to allow dynamic modification of page content previews, with accompanying docs and usage examples (commit a116214b8ca08ca718ad4b0514a9753b6206a8f6). Accompanying quality work: - Minor code-quality improvement: fixed a spacing issue to satisfy code-quality checks during feature work (referenced in the second commit set). Impact: - Establishes robust, non-core extension points for admin customizations, improving flexibility for backend workflows and preview rendering without core changes. - Accelerates developer onboarding with clear docs and examples for event-driven customization. Technologies/skills demonstrated: - PSR-14 event-driven architecture in PHP - API extension practices and documentation generation - Code quality tooling and lint hygiene

Month: 2025-11 — Key features delivered include a comprehensive TYPO3 Documentation Overhaul that refreshed SYS configuration, backend/module development, extension development, site package usage, and extension architecture guidance, backed by multiple commits across main and backport 13.4. Notable items include updates to configuration docs (SYS), overhaul of testing tutorials, extension development how-tos and concepts, and a rename of the top-level module from "list" to "records" to align terminology. In addition, introduced new PSR-14 form handling events to expand flexibility: before a renderable is removed from a form and AfterCurrentPageIsResolvedEvent, with dedicated commits. Overall impact: improved developer onboarding, clearer API guidance, and extended form extensibility; enhanced maintainability across core docs and extension development workflows. No formal bug fixes were recorded this month; focus was on documentation quality and extensibility enhancements. Technologies/skills demonstrated: PHP/TYPO3 Core API documentation authoring, PSR-14 event patterns, extension development workflows, site-package guidance, TCA considerations, collaborative authoring (co-authored by Lina Wolf).
