Worked alongside brilliant engineers to deliver an improved developer experience for customers of an internal framework.• Added TSX web template support to an existing web accessibility linter, alerting developers to violations directly in their editor and at code review. This integration flagged 10+ accessibility concerns in 750+ existing templates, and will highlight more asteams continue to switch to TSX and 10,000+ Soy files are migrated to TSX. This integration was possible by building tooling with TypeScript to extract HTML from TSX templates and sanitize away unsupported syntax.• Introduced a TSX check with TypeScript to block a developer from accidentally overriding the TSX→HTML compiler during development, saving developers from time-consuming debugging of an unhelpful error message.• Enhanced a TSX factory import and declaration check by introducing the flexibility to rename imports to free up the names for use. This cleared the 2 existing violations in the rule’s exemption list, and allowed developers to regain the variable names “element” and “factory”.
