The Challenge

Romania's secondhand fashion market had no digital home.

The Problem

Sellers relied on fragmented social media groups and generic classifieds with no buyer protection, no logistics integration, and no curation. Buyers had no reliable discovery mechanism or seller verification — making trust the biggest barrier to growth.

Our Solution

A full-stack marketplace with listing, bidding, integrated payments (MobilPay/Netopia), automated shipping (Postis AWB generation), seller profiles with ratings, and native mobile apps — giving both sides of the market a seamless, trusted experience.

Key Features

Everything a marketplace needs.

Bidding System

Auction-style offers at 70%+ asking price, rate-limited to 5 bids per 24 hours, with expiration tracking and real-time push notifications.

⟨/⟩

Integrated Shipping

Postis API for automated AWB generation, real-time tracking every 2 hours, Easybox locker delivery, and return shipping flows.

Native Mobile App

Full React Native app with camera integration, push notifications, Apple/Google sign-in, offline state persistence, and OTA updates.

Seller Ecosystem

Public profiles with ratings, follower system, holiday mode, inactivity detection, and automated re-engagement nudges.

9 Background Services

Automated shipment polling, bid expiration, order completion, price drop alerts, push/email/SMS queues, and seller engagement.

Admin Dashboard

Complete operations control — product moderation, order management, commission controls, content CMS, and analytics dashboards.
