Portfolio Build
Scheduling, auctions, bids, and customer messages stay controlled in one real estate workflow system.
This platform keeps appointment scheduling, auction rules and communication state synchronized in one operational workflow.
Property workflow enforcing appointment scheduling, auction rules and real-time state updates
Build Focus
Shows how scheduling conflicts, invalid bids, and fragmented communication are prevented in real-time workflows.
This is a portfolio build used to show architecture, workflow behavior, interface decisions, and product reasoning without presenting it as a client-owned system.
System Behavior
Appointment scheduling is constrained by existing agent bookings
Overlapping appointments for the same agent are rejected under normal sequential operations
Bids outside auction time windows or below the current highest bid are rejected
Auction state progresses through time-driven opening, bidding, and winner resolution
Scheduling, bidding, and communication state remain consistent across listings and user profiles
01
Without an integrated system, a real-estate operation ends up coordinating listings, appointments, bids and communication manually across separate tools and services. The main failures are overlapping one-hour agent appointments, bids being accepted outside valid auction windows or below the current high bid, and user-facing state becoming fragmented between property, appointment, auction and chat activity.
02
The platform combines property inventory, agency structure, agent assignment, appointment scheduling, timed auctions, account management and direct chat across multiple services and databases. Appointments are tracked relationally, auctions and chat run on MongoDB-backed services, RabbitMQ propagates side effects and WebSockets/STOMP power live updates. Availability is derived from persisted appointments and auction windows rather than manual bookkeeping.
Exists to stop scheduling, bidding and communication state from fragmenting across disconnected tools.
03
Appointment creation attempts to block overlapping bookings for the same agent, and each appointment is created with a defined lifecycle state. In auctions, non-bid messages are rejected, bids outside the valid time window are rejected and bids at or below the current maximum are refused. Security rules restrict access to appointments, auctions, chat and some user operations, while chat room creation derives one deterministic room identity from the two participants.
04
Correctness is maintained through role-based access control, transactional appointment state changes, auction time-window checks, a periodic scheduler to open and close auction rooms, synchronous service lookups for enrichment and RabbitMQ-driven denormalization of appointment and bid references into user-facing profiles. The system reduces dependence on staff manually propagating state between domains.
05
The operation gets one place to manage listings, agencies, accounts, appointments, auctions and chat. Backend logic rejects obviously invalid bids, appointment and bid state is propagated into user-facing profiles, live updates reduce manual refresh and auction lifecycle transitions are automated. The result is a platform that handles coordination work that would otherwise be spread across agents, staff and disconnected systems.
Resulting Impact
Listings, appointments, auctions and communication move into one coordinated workflow
Invalid bids are blocked before they create operational noise
Agent scheduling becomes predictable without manual conflict resolution
Users receive live auction and chat updates without manual refresh or coordination
