About DESA Locum
DESA Locum was created based on the latest market trends, innovations, and customer demand. With up-to-date and reliable property data, the platform provides a safe, comfortable, and effective space for investing in real estate. As industry experts, the DESA Locum team accompanies sellers and buyers at every stage of the auction process — from offer presentation and promotional activities through to transaction completion.
Integrating User Management with Auction Mobility
The core challenge was designing and implementing a complete user registration and authentication system that synchronizes with Auction Mobility's platform. When a user registers on desalocum.pl, an account is automatically created on the auction platform — ensuring a seamless experience where users manage their profile in one place while participating in auctions powered by the external engine.

MVP Real Estate Auction Platform
The primary goal was to launch a promotional website and MVP auction platform for DESA Locum. The website needed to present property listings attractively, build trust with potential bidders, and drive registration for upcoming auctions.
React Frontend with Auction Platform Integration
We built the frontend with React.js, creating a responsive promotional website with property listing pages, user registration/login flows, and auction information sections. The backend was powered by Node.js, handling user authentication, session management, and the API integration with Auction Mobility.
Summary
We designed and implemented the DESA Locum promotional website and MVP real estate auction platform. The solution combines a custom user management system with Auction Mobility's bidding engine, delivering a complete digital auction experience for property buyers and sellers.
The project demonstrates how strategic integration with specialized platforms like Auction Mobility can accelerate MVP delivery — allowing the client to launch a fully functional auction platform while focusing resources on the unique value proposition of their real estate expertise.

Frequently Asked Questions
A listings portal advertises properties at fixed prices. Auction software runs the bidding process — registered bidders, deposit handling, real-time bid updates, anti-sniping (auto-extension if a bid lands in the last seconds), reserve prices, buyer's premium, and post-auction settlement. The complexity is in correctness under contention: two bids landing in the same millisecond must both result in a deterministic, auditable outcome.
Auction Mobility is a hosted auction engine that handles bidding, reserve, and settlement workflows. Integrating it means your platform owns the marketing site, listings, and member management, while the auction runtime is delegated to a battle-tested third party. This is the right call when time-to-market matters and the auction logic itself is not your differentiator. Custom auction engines make sense only when you have unusual rules (multi-property bundles, sealed bids, multi-currency settlement).
Real estate is a high-trust transaction; the platform has to project that trust visibly: verified seller identity, complete legal documentation per listing (deed, land registry excerpt, planning), professional photography and floor plans, transparent fee structure (buyer's premium, deposits, closing costs), and clear escrow / settlement timelines. Reviews and references from past buyers, plus a visible legal/operations team, materially affect bid participation rates.
Standard pattern: bidders pre-register and place a refundable deposit (often via Stripe or bank transfer to an escrow account) that authorizes them to bid up to a multiple of that deposit. On winning, the deposit converts toward the purchase; non-winners get refunded automatically. Final settlement happens off-platform via the seller's notary or solicitor, since real estate transfer requires notarized documentation in most jurisdictions. The platform's job is to provide the audit trail.
A common build: React for the bidder and admin UIs, Node.js backend with a relational database (PostgreSQL) for transactional integrity, WebSockets for live bid updates, and a queue-based job runner (BullMQ, SQS) for deposit refunds, email/SMS notifications, and post-auction reporting. The auction engine itself runs as an isolated service so it can be tested and audited independently of the marketing site.
