July 2025 (Layer-Fi/layer-react): Focused on data integrity and stability. No new features released this month; main effort centered on a bug fix in the useLedgerAccounts hook that corrected data transformation by removing double filtering of reversal entries and ensuring proper flattening. This fix prevents incorrect ledger displays and downstream calculations, reducing edge-case errors for end-users. Commit d65e4d5afbeb3e976a91dabb0cecb2f4d89f7568 ("dont filter twice") implemented the change. Impact: more reliable ledger data, improved user trust, and reduced troubleshooting time for UI data issues. Technologies/skills demonstrated: React hooks, JavaScript data processing, debugging, and maintainable commit-driven workflow.

Apr 2025: Implemented proactive bank connectivity alerts in Layer-Fi/layer-react, including a bank account connectivity notification workflow, a status-fetching React hook, and a dedicated notifications UI. Improved the reconnect experience by conditionally rendering the 'Reconnect bank accounts' action only when an onClick is provided, reducing UI clutter and preventing non-actionable UI. This work is backed by two commits: c5e2ffc07783a7bb0818f643b3d2959e9d484fc5 (Notification for accounts being disconnected) and bccfdc69dafc6a34e121995d1cb18a0f0ee24a65 (hide button when no onClick provided).
