Architecture & System Design

ZENI uses a Next.js product interface backed by a Node.js API and PostgreSQL. Socket.IO distributes listing-state changes and direct agent-to-user updates without repeatedly polling the database.

// Commit the state change only when the listing is still available.
const listing = await db.oneOrNone(
  `UPDATE listings
   SET status = 'PENDING_VERIFICATION', locked_by = $2
   WHERE id = $1 AND status = 'AVAILABLE'
   RETURNING id`,
  [payload.listingId, payload.userId]
);

if (!listing) throw new Error("Listing is no longer available");
io.to(`listing:${listing.id}`).emit("listing:locked", { id: listing.id });

Outcome

Tested with 12 property agents, validating the core real-time property discovery and transaction readiness workflow.
