Project Description

Built CORA (Customer Operations and Response Automation), a sophisticated customer service application combining traditional workflow management with cutting-edge AI capabilities. The platform leverages RAG (Retrieval-Augmented Generation) architecture to provide intelligent, context-aware responses to customer queries while maintaining workflow orchestration for complex banking processes. Features semantic caching, vector search, and agent-driven automation to improve efficiency and reduce costs.

Architecture

Pattern:

RAG-based AI architecture with workflow orchestration

Data Flow:

Query → Semantic Cache Check → Vector Search → Knowledge Retrieval → LLM Generation → Response
Key Features
  • RAG-based intelligent query answering
  • Semantic search combining full-text and vector retrieval
  • Semantic caching with embedding similarity detection
  • Agent-driven workflow automation
  • Context-aware response generation
  • Automated summarization and analytics
  • Action item extraction from conversations
  • Smart tagging and categorization
Impact & Achievements

Impact:

  • Reduced average response time from 5 minutes to 1.2 seconds
  • Decreased AI operational costs by 60% through semantic caching
  • Automated 40% of routine customer service tasks
  • Improved customer satisfaction scores by 35%
  • Enabled 24/7 intelligent customer support

Key Achievements:
