Multi-Modal AI Support Agents

using (OpenAI + SQL + Speech) with n8n

Developed and productionized a suite of AI-powered customer service agents capable of interacting with users across multiple channels including live chat, email, SMS, and voice calls. Leveraged OpenAI’s GPT models integrated with a legacy Microsoft SQL Server system to deliver real-time, contextual responses to complex business inquiries.

Using n8n as the orchestration engine, the system dynamically translated customer questions into SQL queries with guardrails, enabling accurate data retrieval through natural language. Speech-to-text was layered in to handle live voice input, allowing seamless spoken interaction. As a result, the solution cut support ticket volume in half and enhanced response speed and quality across all channels.

  • 1
    Improved Response Time 40%

    Improved average response time by over 60% and increased customer satisfaction scores.

  • 2
    Reduced Human Workload 40%

    Automated over 40% of inbound support workload, freeing human agents for complex cases.

  • 3
    Improved Security Via Constraints

    Maintained full auditability and safety via query context constraints and fallback logic.

This intelligent automation platform reduced customer support costs significantly, cut average response times from several hours to seconds, and created a scalable foundation for future AI-assisted operations.

Seamless Automation of Customer Queries

n8n served as the central nervous system for orchestrating the flow of data between AI models, legacy databases, APIs, and customer-facing communication channels.

I leveraged n8n’s low-code environment and node-based architecture to build a series of modular, reusable workflows that managed everything from natural language input parsing to SQL query execution, error handling, and intelligent escalation.

Reduced Costs While Improving Customer Experience

By offloading repetitive and data-driven questions to AI workflows, the existing human team was freed up to focus exclusively on edge cases and higher-value interactions. This not only reduced labor costs but also resulted in faster response times and a smoother, more consistent customer experience across all channels.

This intelligent automation platform reduced customer support costs significantly, cut average response times from several hours to seconds, and created a scalable foundation for future AI-assisted operations.

  • Visual Workflow Design: Allowed rapid iteration and testing of complex logic without traditional code deployment cycles.
  • Native OpenAI and DB Integration: Simplified connection to both LLM APIs and structured data sources in a single tool.
  • Flexible Error Handling: Added retry loops, conditional branches, and alerting for edge cases and critical paths.
  • Contextual Query Building: Used function and merge nodes to dynamically assemble safe queries based on prior conversation memory.
  • Composable Architecture: Created modular sub-workflows for tasks like transcription handling, sentiment analysis, and escalation, improving maintainability.
