September 2025 focused on strengthening type safety, expanding analytics capabilities, and stabilizing CI/test workflows for ProteinPaint across two repositories. Key work included extending NumericTerm typing to cover ssGSEA, enabling TwRouter support for ssGSEA and metaboliteIntensity, and modernizing the TermSetting API with a class-based architecture and new UI scaffolding. GeneExpression typing gained a term.kind property; numerous quality-of-life and infrastructure improvements reduced build/test noise and improved feedback cycles. A broad set of bug fixes improved data access paths, UI correctness, and render stability, laying a solid foundation for future analytics features. Tech leadership demonstrated: TypeScript typing, refactoring to classes, Rx-based patterns, and CI automation. Business impact: lower defect rates, faster validation of new analytics workflows, and improved maintainability for long-term scalability.
