March 2026 delivered stability, maintainability, and reliability improvements for Expensify-App, with a focus on offline workflows, API/UI consistency, and code hygiene. The work reduced outage risk, improved user experience in invoicing scenarios, and accelerated future development through cleaner submodule management and formatting.

February 2026: Delivered Release 2.2 toggle behavior progress, updated split logic to match OD, and UI polish for Central Invoicing, while strengthening CI, submodule maintenance, and test coverage. Key outcomes include stabilization of flows (public domain guard, review adjustments) and preventing NaN in split inputs, along with settlement API call deduplication. Business impact: faster release readiness for 2.2, fewer runtime errors, and improved data integrity in invoicing. Demonstrated technologies: frontend logic, tests, CI pipelines, localization, type checks, and code quality tooling.
