@shivamhardia

I will treat your Node.js and React POS system as a revenue-critical tool where sales must continue even when internet drops, printers disconnect, or synchronization is delayed during busy store hours. Are you currently storing transactions locally in IndexedDB or another offline store so i can design the sync layer safely from day one? Recently i worked on a production platform managing structured inventory and daily operations where reliability under unstable connectivity was essential. In that system i handled background sync and device workflows used by real teams every day without stopping operations. The plan is to introduce a queue-based sync engine, a device-agnostic printing gateway, and staged performance refactoring so new features do not disrupt live sales. The tricky part in POS systems is reconciling stock counts correctly after multiple offline transactions. If you can share repository access or a staging environment, I will review the current flow and propose the safest upgrade path for these enhancements.
