Work History

March 2026

24 Commits • 7 Features

Mar 1, 2026

March 2026 — consolidated expenses UI improvements, expanded expense type support, and hardened the expense flow across devices. Delivered inline IOU amount input, added support for other expense types, implemented a new flow without rendering the amount (with tests), refined currency handling, and completed extensive code quality work (linting, typing, formatting). UX reliability fixes were implemented (preserved input focus, padding tweaks, mobile Safari scroll), reducing errors and increasing user confidence. Business impact: faster expense capture, fewer form errors, and more predictable multi-currency processing, with maintainable codebase.
