Harmony: AI-Powered Data Reconciliation Built on Databricks

How Elitmind Leveraged Databricks Data Intelligence Platform to Transform Customer Data Quality

‍

The Challenge: when bad data costs real money

‍

A major energy provider faced a costly problem: their customer address database was a mess. Hundreds of thousands of records contained incomplete streets, missing cities, and inconsistent formatting. Mass mailing campaigns regularly failed - letters returned, deliveries missed, customers frustrated.

Manual data cleansing wasn't working. With 100,000+ addresses needing verification for each campaign, the team spent days hunting down corrections, cross-referencing postal codes, and still missed errors. They needed something faster and smarter.

‍

Introducing Harmony: AI-Powered Reconciliation

Developed by Elitmind, Harmony is an AI-powered data reconciliation platform that ensures customer records are accurate, consistent, and unified across all enterprise systems. Built on the Databricks Data Intelligence Platform, Harmony automatically validates, cleanses, and corrects customer address data against official territorial registers.

The solution leverages Databricks Mosaic AI and other advanced AI capabilities to deliver what manual processes never could: intelligent, scalable, and precise data reconciliation that works in real-time.

The Technical Architecture

Harmony's architecture demonstrates the power of combining AI with enterprise-grade data processing:

‍

Core Components:

1. Databricks Data Intelligence Platform At the heart of Harmony lies Azure Databricks, providing:

• Scalable and secure data processing infrastructure

• Unified analytics and AI capabilities

• Enterprise-grade governance and compliance
• ‍

2. AI-Powered Processing Modules Built on Databricks, Harmony incorporates four specialized AI modules:

• Data Cleansing: Automatically identifies and corrects formatting inconsistencies

• Intelligent Matching and Validation: Uses AI to match records across systems

• Address and PEP Reconciliation: Verifies addresses against official territorial registers (TERYT in Poland)

• Data Quality Report Generation: Provides comprehensive quality metrics

‍

3. Integration Layer Harmony seamlessly connects to:

• Enterprise domain systems (Data Warehouse  and other customer databases)

• Official governmental databases  

• External AI services (OpenAI GPT for advanced natural language processing)

• Azure Storage for secure data persistence

‍

How AI Transforms Data Reconciliation

Traditional data reconciliation relies on exact matching and rigid rules. Harmony's AI-powered approach understands context and handles real-world data complexity:

Example 1: Location Correction

Original: CICHA 7/100A, 35-326
AI-Corrected: RZESZÓW (identified missing city)

Example 2: Complex Address Resolution

Original: NIEDZIALKOWSKIE.225/271-14
AI-Corrected: UL. NIEDZIAŁKOWSKIEGO 225/271-14 (full address reconstruction)

The AI engine understands abbreviations, typos, missing components, and regional variations - delivering corrections that would take human operators hours to research and verify.

‍

Proven Results: Speed Meets Accuracy

In a production deployment for mass mailing operations, Harmony demonstrated exceptional performance:

• 100,000 unmatched customer records processed

• Completed in 1 hour 11 minutes

• Target time: 2.5 hours

• Result: 53% faster than required

‍

This isn't just about speed - it's about delivering verified, compliant data at scale. Every address was validated against the national territorial standard, ensuring deliverability and regulatory compliance.

‍

The Databricks Advantage

‍

Building Harmony on Databricks Data Intelligence Platform provided critical capabilities:

‍

Scalability

Process millions of records without performance degradation. Databricks' distributed computing architecture ensures consistent performance regardless of data volume.

Security

Enterprise-grade security and compliance built-in. Customer data remains protected throughout the reconciliation process.

AI Integration

Native support for AI/ML workflows through Mosaic AI, enabling sophisticated data intelligence without complex integration.

Unified Platform

Single platform for data engineering, analytics, and AI—eliminating the complexity of managing multiple tools and systems.

‍

Business Impact

The implementation of Harmony delivered measurable business value:

Operational Efficiency: Reduced data preparation time by over 50%, enabling faster campaign execution and improved resource utilization.

Cost Reduction: Fewer returned mailings, reduced manual correction efforts, and improved first-contact success rates.

Data Quality: 100% compliance with national address standards, ensuring consistency across all customer touchpoints.

Scalability: Ability to handle growing data volumes without proportional increases in processing time or costs.

‍

Looking Forward

Harmony represents more than a data cleansing tool - it's a demonstration of how AI-powered platforms can transform fundamental business operations. By combining Databricks Data Intelligence Platform with advanced AI capabilities, Elitmind created a solution that delivers accuracy, speed, and scale.

As enterprises continue to grapple with data quality challenges across increasingly complex systems, solutions like Harmony point the way forward: intelligent automation built on robust, scalable platforms that put AI to work solving real business problems.
