The client's existing cloud-based POS cost Rs. 80,000/year and was completely unusable during Sri Lanka's 2022 power cuts and internet outages — directly causing lost sales every day.
Built a cross-platform Electron app with SQLite for local-first storage, automatic background sync when online, barcode scanner integration, thermal printer driver for receipts, and a role-based multi-cashier system.
Zero downtime during power cuts. Rs. 80,000/year in licensing eliminated. Successfully deployed to 3 branches with no training issues.
