Building a Workflow-Based Property Search Engine with Gemini 2.0 Flash 

The Vision: Exceeding Traditional Property Search in Dubai

Bridging this gap through a sophisticated workflow-based approach that maintains intelligence and efficiency.

The Challenge We Tackled

Consider how a person might describe their ideal home to an estate agent in Dubai:

I'm searching for a family-friendly apartment close to excellent schools, filled with natural light, and conveniently located near public transport.

Traditional search systems would struggle to interpret these human preferences, forcing users to translate their needs into predefined filters and tick boxes.

Our goal was ambitious but transparent: create a system that could think like an estate agent whilst operating at AI speed and scale. This meant developing a workflow engine that could:

• Harness Gemini 2.0 Flash models for efficient processing
• Orchestrate multiple specialised AI agents.
• Process complex property requirements naturally.
• Deliver results at production scale and speed.

Technical Architecture: A Workflow-Based Method

After an intensive 24-hour development sprint, we arrived at a workflow-based architecture that mirrors how human estate agents process property enquiries, enhanced by Gemini 2.0's capabilities. This approach breaks down the complex task of property matching into discrete, manageable steps, each handled by specialised AI components.

Core Components

Our solution leverages a three-tier workflow architecture that combines the best of human expertise with AI capabilities:

• Intelligent Query Processing
• Multi-Agent Orchestration
• Keyword Extraction Agent
• Property Research Agent
• Listing Generation Agent
• Result Synthesis Engine

The Power of Workflow-Based Processing

Its ability to handle complexity through composition makes our workflow approach particularly powerful. Each step in the workflow is independent yet interconnected, allowing for:

interface WorkflowStep<T, R> {
     id: string;
     execute: (input: T) => Promise<StepResult<R>>;
     validate: (input: T) => Promise<boolean>;
     retryConfig: RetryConfiguration;
}

1. Parallel Processing: Multiple AI agents can work simultaneously on different aspects of the search
2. Incremental Refinement: Results are continuously improved as they flow through the workflow
3. Flexible Adaptation: New capabilities can be added by introducing new workflow steps

Beyond Basic Search

Our implementation pushes the boundaries of what's possible in property search technology. Here's how we've tackled some of the most challenging aspects:

1. Error Resilience

Implemented retry mechanisms with exponential backoff

Automatic error recovery

Comprehensive logging and monitoring

1. Type Safety

interface PropertyWorkflowData  {
  query: string;
  metadata: WorkflowMetadata;
  results: PropertySearchResult[];
}

1. Performance Optimisation

• Asynchronous processing
• Efficient resource utilisation
• Detailed performance metrics
• Customised ranking algorithms
