ElectroTrack — SaaS POS for Electronics Retail
ElectroTrack is a multi-tenant SaaS POS system designed for electronics shops. Every phone, laptop, or gadget is tracked at the individual unit level using serial numbers — so you always know exactly which device was sold to whom, when the warranty expires, and whether a return is fraudulent. It ships as two apps: electrotrack-api — NestJS REST API with Prisma + PostgreSQL (Supabase) electrotrack-pos — React + Vite SPA (cashier / owner frontend)
Technical challenge
A multi-tenant Point-of-Sale and inventory management platform built for electronics retailers. Premium dark UI, serial-number tracking, warranty management, AI insights, and real-time sales analytics — all in one system.
