This paper presents a novel cloud-native conversational business intelligence platform that integrates Large Language Models with real-time sales analytics and machine learning-based forecasting capabilities. Traditional business intelligence systems require technical expertise and predefined queries, limiting accessibility for business users. Our solution addresses this gap by implementing a natural language interface powered by Groq\'s Llama 3.1 70B model, enabling non-technical stakeholders to extract insights through conversational queries. The system architecture employs AWS serverless technologies including Lambda functions for data ingestion and processing, S3 for scalable data lake storage, API Gateway for RESTful endpoints, and AWS Glue for ETL operations. Real-time data ingestion captures sales transactions immediately, while batch processing aggregates historical data daily. The platform incorporates Facebook Prophet algorithm for time-series forecasting with confidence intervals spanning 30, 60, and 90-day horizons, capturing daily, weekly, and yearly seasonality patterns. The conversational AI component analyzes aggregated sales data across 785 days comprising 14,486 transactions totaling 8.5 million dollars in revenue, providing intelligent responses to queries about regional performance, product trends, and category analytics. A dual-mode Streamlit dashboard enables seamless switching between local CSV analysis and cloud-based AWS data sources, featuring interactive Plotly visualizations, date range filters, and real-time AWS data ingestion capabilities. The system demonstrates production-ready scalability while maintaining cost-effectiveness through AWS Free Tier utilization and Streamlit Community Cloud deployment. Evaluation metrics show ultra-fast LLM inference at 500 tokens per second and accurate forecasting with minimal mean absolute percentage error, validating the platform\'s effectiveness for enterprise sales analytics and strategic decision-making.
Introduction
a conversational business intelligence (BI) platform that allows users to interact with sales data using natural language instead of technical tools like SQL or dashboards.
The main problem addressed is that traditional BI systems require technical expertise, making it difficult for non-technical business users to access and analyze data. The proposed solution uses Large Language Models (LLMs) to enable conversational querying of enterprise data, combined with cloud-native serverless architecture on AWS for real-time scalability.
The system integrates:
Groq LLM (Llama 3.1 70B) for fast natural language query understanding and response generation
AWS serverless tools (Lambda, API Gateway, S3, Glue, Athena) for data ingestion, storage, and processing
Facebook Prophet for time-series forecasting of sales trends
Streamlit dashboard for interactive visualization and dual-mode (local + cloud) analytics
Key functionalities include:
Real-time sales data ingestion and processing
Natural language querying of business data (e.g., revenue, product performance, regional sales)
Forecasting future sales with confidence intervals
Interactive dashboard for visualization and insights
Performance results show:
~1.2 second response time for queries
High-speed LLM inference (500+ tokens/sec)
Forecast accuracy with MAPE between 8%–15% depending on horizon
Low-cost deployment (~$15/month using AWS Free Tier)
Conclusion
This paper presented a production-ready conversational business intelligence platform integrating LLM-powered natural language interfaces with real-time sales analytics and machine learning forecasting. The system successfully demonstrates that cloud-native serverless architectures can deliver enterprise-grade analytics capabilities while maintaining cost-effectiveness and scalability.
The integration of Groq\'s ultra-fast LLM inference with AWS data processing pipelines enables business users to extract insights through natural conversation, eliminating technical barriers to data-driven decision-making.
Future work includes implementing multi-modal analytics combining text and visualization in AI responses, fine-tuning domain-specific LLMs for industry verticals, and extending forecasting capabilities to include causal impact analysis and anomaly detection. Additionally, integration with enterprise data warehouses and support for streaming analytics at sub-second latency represent promising research directions.
