DWICE – The Smart Marketplace for Vinyl Lovers
A next-generation, AI-powered marketplace for buying, selling and discovering vinyl records — designed for Europe, built with community at its core.

The Vision: Music Deserves Better
In a world of infinite playlists and background noise, the connection between people and the music they love has become diluted. Vinyl collectors are passionate — but the platforms they rely on are outdated, fragmented, and friction-heavy.
DWICE set out to reinvent vinyl record trading with a platform that is designed for Europe, built with a community mindset, and powered by AI. The founders came to us with a bold vision: create a single marketplace where collectors can trade, discover, and connect around music — through a simple, modern, tech-driven interface.
What We Built
We designed and developed the full DWICE platform from the ground up — a cross-platform ecosystem spanning mobile, web, and backend, all working together seamlessly.
Mobile App
React Native / Expo app for iOS and Android. Features AI-powered record scanning (photo, barcode, catalog number), collection management, built-in negotiation, and a Spotify/YouTube audio player.
Web Dashboard
Next.js admin dashboard for sellers and power users. Includes bulk CSV import, advanced analytics, order management, and a full business onboarding flow.
Backend API
.NET 8 Web API with PostgreSQL, Redis caching, Hangfire background jobs, and Stripe Connect for marketplace payments with split payouts to sellers.
Smart Shipping
Integrated SendCloud logistics with standardized rates, sustainable parcel points across Europe, embedded insurance, and transparent fee calculation — no surprises.



AI at the Core
DWICE isn't just a marketplace — it's an intelligent one. We embedded AI throughout the experience:
- Record Recognition — snap a photo and let AI identify the release, artist, and catalog number instantly.
- Smart Curation — personalized recommendations that fit your taste, powered by technology that listens like a human, not an algorithm.
- Intelligent Classification — automated grading suggestions and pricing guidance based on market data.
- Search Enhancement — fuzzy matching across artist names, transliterations, and catalog numbers for effortless discovery.
The Tech Stack
Building a marketplace at this scale required making deliberate technology choices that balance speed, reliability, and cost-efficiency:
- React Native with Expo — one codebase for iOS and Android, with native performance.
- Next.js 14 — server-rendered web dashboard with Radix UI components and Tailwind CSS.
- .NET 8 with FastEndpoints — high-performance API with Entity Framework Core and PostgreSQL.
- Stripe Connect — marketplace payments with split payouts to sellers.
- Redis — real-time caching for search, pricing, and session management.
- Hangfire — background job processing for email notifications, analytics, and data sync.
- SendCloud — automated shipping label generation and parcel tracking across Europe.
