Selling or buying used electronics often feels risky, uncertain device condition, confusing prices, and no clear process. Harage set out to fix that for the Qatar market by building a professional, app‑based platform that handles the heavy lifting: quality checks, pricing, logistics, and trust. From the customer side, the app is straightforward. Sellers can submit details about their device in just a few steps, receive a fair market evaluation, and schedule pickup or drop‑off anywhere in Qatar. Once Harage completes inspection and verification, the device enters the marketplace as a certified listing. Buyers, on the other hand, can browse a curated catalog of used smartphones, laptops, tablets, and other electronics, each with clear grading, real product photos, and transparent pricing. Because Harage oversees inspection, grading, packaging, and delivery, buyers know exactly what they’re getting, and sellers don’t need to worry about negotiations or logistics. Under the hood, the customer apps are built natively in Kotlin (Android) and Swift (iOS). A Node.js backend with MongoDB powers product listings, evaluations, orders, and user accounts, while an HTML/CSS/jQuery/Bootstrap‑based admin panel gives the Harage team full control over inventory, pricing rules, order flows, and customer support.

As Harage scaled its customer‑facing marketplace, the team needed more than spreadsheets and basic dashboards to stay in control. They required a secure, purpose‑built tool where admins, operations staff, and managers could oversee every part of the business: which devices are incoming, what stage each order is in, how pricing is applied, and how logistics are progressing. The Harage Superadmin app was created exactly for that. Using the mobile apps (Kotlin for Android and Swift for iOS), authorised team members can log in and see key operational data in real time, new seller requests, devices awaiting inspection, approved listings, orders in progress, and completed deliveries. They can update statuses, adjust prices where allowed, review quality‑check results, and handle escalations without needing a laptop. Alongside the mobile apps, a browser‑based admin panel built with HTML, CSS, jQuery, and Bootstrap offers a richer, desktop‑oriented view for office teams. Both the apps and panel connect to a Node.js backend with MongoDB, which stores users, devices, inspection reports, pricing rules, and order flows. This combination gives Harage a centralised “brain” for operations, accessible from both mobile and web.
