Dewasinghe Jewellery POS

A jewellery counter that both sells and rents, with deposits, due dates and returns handled properly, now trading under two retailers’ brands.

Cross-platform desktop point of sale in Tauri and Rust, with a ShadCN interface and real-time sync through Supabase so the shop floor and back office never disagree. Rentals are first-class alongside sales: deposits, due dates and returns are tracked through the same till.

What I did

  • Packaged a Rust + Tauri desktop shell for Windows, small footprint and fast start.
  • Designed and built the ShadCN interface around real counter workflows.
  • Set up real-time Supabase sync so stock and sales stay consistent across devices.
