JSR

JSR is a Windows desktop application for an agricultural trading business, used to manage daily purchases, sales, stock, and party ledgers. It is built to keep working with no internet connection and to sync a backup to the cloud whenever a connection is available. It ships as a desktop installer, not a website — there is no public URL, and the executable is not offered for download here.

What I did

• Architected the app on Electron.js with a multi-document (MDI) interface so operators can work across several ledgers and entries at once.
• Implemented an offline-first local data layer on SQLite with a background cloud-backup and restore routine.
• Built the React front-end for billing, stock, and reporting, plus print-ready invoice and statement layouts.
• Packaged and distributed the signed Windows installer with auto-update support.
