February 2026 — Expensify-App (callstack-internal/Expensify-App) delivered impactful UI/UX updates, stability fixes, and quality improvements that boost onboarding, reliability, and accessibility. Key features include UI/UX visual & asset updates for Uber for Business invite confirmation and the Mobile-Expensify module. Major bugs fixed span distance checks, modal context handling for multiple modals with useRef, distance unit changes, import issues, TypeScript errors, and control flow. Additional improvements cover accessibility and translations, plus code cleanup and refactoring to improve readability and maintainability.

January 2026 monthly highlights: Delivered core localization, GPS/location reliability, and mobile architecture improvements that directly boost user experience and business value. Key outcomes include expanded localization (Spanish and German), robust Precise Location API improvements, Android foreground service integration to support GPS trips, foundational Mobile-Expensify core module initialization, and a strong emphasis on code quality and CI stability.

November 2025: Delivered a targeted documentation correction for Onyx.merge() in Expensify/react-native-onyx to accurately reflect employee-list merge behavior. This fix aligns docs with the actual implementation, improving developer onboarding and reducing integration errors. No new features were released this month; the primary work was documentation quality and correctness, reinforcing maintainability and reducing support overhead.

October 2025 focused on unifying and hardening the SelectionList-driven UI across margelo/expensify-app-fork and callstack-internal Expensify-App. Key features delivered include a broad migration of the SelectionList component across IOURequest steps, language/theme settings, notifications, and various settings pages, plus header extraction and UI labeling improvements (notably the “Choose a workspace” label). The work also introduced translations for new UI strings and improved localization readiness. Major bugs fixed include stabilization of label usage (restoring and regressing Workspaces labels as needed), robust handling of ONYX data (canBeMissing) and custom date rendering, and multiple lint/type fixes with unit-test reruns. Additional code health improvements included removing legacy splitPayer functionality and consolidating SelectionList usage across additional pages. Overall impact: improved UI consistency, maintainability, localization readiness, and reliability, enabling faster, safer UI changes with fewer regressions. Technologies/skills demonstrated: React/TypeScript, ONYX state handling, component design and refactors, internationalization/localization, linting/CI hygiene, and unit testing.
