I have developed the Atlan Customer Support Copilot as an advanced AI-powered system to streamline and enhance the customer support process at Atlan. Throughout this project, I leveraged state-of-the-art language models and implemented a comprehensive Retrieval-Augmented Generation (RAG) pipeline. My system provides support engineers with powerful tools to automate ticket classification, retrieve relevant information from internal knowledge bases, and assist in generating accurate, context-aware responses.

1. Raw tickets are loaded from MongoDB Raw Tickets Collection
2. Classification Agent processes tickets using Gemini API
3. Results are stored in MongoDB Processed Tickets Collection
4. Dashboard displays processed tickets with analytics
5. Chat interface uses processed ticket data for enhanced responses

1. User query enters through Chat Interface
2. Orchestrator manages multi-agent workflow
3. Classification Agent analyzes query intent
4. RAG Agent searches Qdrant vector database
5. Response Agent generates final answer with citations
6. Processed results are stored in MongoDB for future reference

I built the copilot around seven main functional pillars that I carefully designed and implemented, all now fully operational:

When I implemented the ticket classification system, I ensured that upon receiving any new support ticket (whether from a user query in the chat interface or from a database), my system automatically classifies it based on three key criteria that I identified as most important:

• Topic: I designed this to identify the primary subject of the ticket (e.g., Connector, Lineage, API/SDK).
• Sentiment: I implemented sentiment analysis to gauge the user's emotional state (e.g., Frustrated, Curious).
• Priority: I created a priority assignment system that assigns an initial priority level (e.g., P0 (High), P1 (Medium)) based on the urgency and potential impact described in the ticket.

Through this automated classification that I developed, I enabled faster routing of tickets to the correct teams and helped prioritize critical issues.

For queries that require factual information, I implemented a powerful RAG pipeline that I'm particularly proud of. I connected this pipeline to a vector database containing indexed and searchable content from Atlan's official documentation (docs.atlan.com) and developer portal (developer.atlan.com).

When a user asks a question, my RAG agent follows this process that I designed:

1. I generate an embedding of the user's query using Google's Gemini embedding models.
2. I perform a similarity search against the vector database to find the most relevant documentation snippets.
3. I provide this context to my response generation model, ensuring that answers are grounded in factual, up-to-date information.

The final component I implemented is a response generation agent that synthesizes the information retrieved by my RAG pipeline into a coherent, human-readable answer. I designed this agent to:

• Answer questions using only the provided context to ensure accuracy.
• Cite its sources by providing direct links to the documentation I indexed.
• Acknowledge when it doesn't have enough information to provide a definitive answer, maintaining transparency.

I implemented a comprehensive unified data persistence layer that stores all ticket data in a single MongoDB collection with rich metadata and advanced analytical capabilities:

• Unified Ticket Schema: All tickets are stored in a single tickets collection with a processed boolean field. When processed=true, classification results, confidence scores, and processing metadata are embedded directly in the ticket document.
• Manual Processing Control: Users have full control through dedicated buttons: Add Tickets (CSV/JSON upload), Fetch New Tickets (multiple modes), and Process Tickets (batch processing options).
• Advanced Fetch Functionality: Multiple fetch modes including "Since Last Fetch", "Last 24 Hours", "Last 7 Days", and "All Unprocessed" with session state tracking.
• Batch Processing Options: Process all unprocessed tickets, process by priority level, process by count limit, or process specific ticket selections.
• Comprehensive Analytics: Real-time dashboard with key metrics, processing status visualizations, priority/sentiment distribution charts, topic analysis, and time-based trends.
• Advanced Filtering: Multi-select filters for priority and sentiment, date range filtering, and text search with database-level queries.
• Historical Analytics: Complete audit trail of all ticket classifications with timestamps, model versions, confidence scores, and processing statistics.

I implemented a comprehensive ticket management system with advanced features:

• Clickable Tickets: Each ticket card is clickable and opens a detailed view
• Multipage Navigation: Seamless navigation between tickets view and detailed ticket pages
• AI-Powered Resolution: Automated ticket resolution using RAG for eligible topics
• Team Routing: Intelligent routing to appropriate teams for non-RAG topics
• Detailed Analysis Display: Complete AI analysis with confidence scores and metadata

I created a sophisticated user interface with multiple views:

• Dashboard: Analytics and batch processing capabilities
• Tickets View: Card-based layout with advanced filtering
• Ticket Detail View: 4-tab comprehensive ticket analysis
• Chat Interface: Real-time AI conversations with citations
• Responsive Design: Works seamlessly across devices

I integrated multiple knowledge sources for comprehensive coverage:

• Atlan Documentation: Primary knowledge base at https://docs.atlan.com/
• Developer Hub: Technical documentation at https://developer.atlan.com/
• Vector Database: Optimized storage with Qdrant for fast retrieval
• Semantic Chunking: Intelligent document segmentation for better context

I designed the system with enterprise-grade features:

• Unified Database Schema: Single MongoDB collection with embedded processing data
• Advanced Analytics: Real-time statistics and comprehensive reporting
• Error Handling: Comprehensive error recovery and user feedback
• Performance Optimization: Optimized queries and responsive UI
• Scalability: Designed to handle enterprise workloads

The following technologies were used to build the application, as specified in the initial project brief:

• Backend Language: Python 3.11+
• AI Orchestration: LangGraph
• Large Language Models (LLM): Google Gemini Family
  • gemini-2.5-flash: Used for fast and efficient tasks like ticket classification.
  • models/text-embedding-004: Used for generating text embeddings.
• Frontend Framework: Streamlit
• Vector Database: Qdrant
• Primary Database: MongoDB Atlas
• Web Scraping: requests and beautifulsoup4
• Async MongoDB Driver: motor

Decision: The core logic was structured as a multi-agent system orchestrated by LangGraph, rather than a monolithic chain.

Rationale:

• Specialization: This allows for creating specialized agents (ClassificationAgent, RAGAgent, ResponseAgent) that are experts at a single task. This improves accuracy and makes the system easier to debug and maintain.
• Modularity: Each agent can be developed, tested, and improved independently. For example, the RAG agent's search logic can be enhanced without affecting the classification agent.
• Explicit State Management: LangGraph's StateGraph provides a clear, typed CopilotState dictionary that tracks the progress of a query through the system. This makes the data flow transparent and predictable.

Trade-off: This approach introduces slightly more complexity upfront compared to a simple LLM chain, as it requires defining the graph structure, nodes, and edges. However, this pays off in scalability and maintainability.

Decision: The application implements explicit delays (asyncio.sleep) to handle API rate limits, particularly in the UI dashboard and the agent orchestrator.

Rationale:

• During testing, concurrent API calls to the Gemini free tier resulted in 429 rate limit errors.
• The most robust solution in the given environment was to process API-dependent tasks sequentially with a delay, ensuring that the application remains within the free tier's requests-per-minute quota.
• A centralized delay node was added to the LangGraph orchestrator to manage the timing between calls to different models (flash vs. pro), which may have separate rate limit pools.

Trade-off: This significantly increases the processing time for batch operations (like classifying all tickets in the dashboard) and the response time for the chat interface. A production system with a paid API plan could use more sophisticated, concurrent processing with a proper rate-limiting library.

Decision: The data ingestion pipeline (scraping, processing, embedding) is implemented as a separate, runnable script (scripts/scrape_and_embed.py).

Rationale:

• Populating the vector database is a heavy, one-time or periodic task. Decoupling it from the main application runtime prevents it from blocking the UI or API.
• It allows for the ingestion pipeline to be run on a schedule (e.g., a nightly cron job) to keep the knowledge base up-to-date without redeploying the main application.

Trade-off: This means the knowledge base is not updated in real-time. There will be a delay between when documentation is published and when it becomes available to the RAG agent.

Decision: Implemented a comprehensive single-collection MongoDB architecture with embedded processing data, advanced analytics, and enterprise-grade features.

Rationale:

• Unified Schema: Single collection eliminates complexity and data synchronization issues, providing a clean, maintainable architecture.
• Manual Processing Control: Users have complete control over ticket processing through an intuitive button-based interface, preventing unwanted automatic processing.
• Embedded Classification Data: Classification results embedded directly in ticket documents maintain data locality and enable complex queries.
• Advanced Fetch Functionality: Multiple fetch modes with session state tracking enable efficient ticket discovery and management.
• Batch Processing Options: Flexible processing modes (all, by priority, by count limit) improve workflow efficiency for different use cases.
• Comprehensive Analytics: Real-time statistics, interactive charts, and advanced filtering provide deep insights into ticket processing patterns.
• File Upload System: Robust CSV/JSON import with validation and preview ensures data quality and user experience.
• Proper Tag Definitions: AI classification now uses structured tag definitions for accurate, meaningful categorization.
• Audit Trail: Complete processing history with timestamps, confidence scores, and metadata enables compliance and debugging.

Implementation Details:

• Schema Structure: processed boolean field with embedded classification, confidence scores, and processing metadata.
• Query Optimization: Efficient MongoDB queries for filtering, searching, and analytics.
• Session Management: Streamlit session state for tracking user interactions and fetch history.
• Caching Strategy: Smart caching with TTL for analytics and manual refresh capabilities.
• Error Handling: Comprehensive error handling with user-friendly feedback and graceful degradation.

Trade-off: Slightly larger document sizes for processed tickets, but provides superior data consistency, query performance, and user experience. The unified approach significantly simplifies the codebase while delivering enterprise-grade functionality.

Decision: Implemented a multipage Streamlit application with specialized views for different user workflows.

Rationale:

• User Experience: Separate pages for dashboard analytics, ticket browsing, and detailed views provide better organization and performance
• Scalability: Each page can be developed independently and optimized for its specific use case
• Navigation: Clear navigation patterns with session state management for seamless user flow

Implementation Details:

• Dashboard Page: Analytics, batch processing, and system overview
• Tickets View Page: Card-based ticket browsing with advanced filtering
• Ticket Detail Page: 4-tab comprehensive analysis (Details, AI Analysis, Response, Internal)
• Session State: Proper state management for ticket selection and navigation

Trade-off: Increased complexity in state management, but provides superior user experience and maintainability.

Decision: Designed a responsive card-based layout for ticket display with visual status indicators and pill-style tags.

Rationale:

• Visual Hierarchy: Cards provide clear visual separation and organized information display
• Status Indicators: Color-coded priority badges and status pills enable quick assessment
• Responsive Design: Grid layout that adapts to different screen sizes
• Interactive Elements: Clickable cards with hover effects and clear call-to-actions

• Click Navigation: Seamless navigation to detail views with session state

Trade-off: Slightly more complex CSS/HTML generation, but significantly improves information density and user interaction.

Decision: Implemented multi-level filtering system with real-time updates and persistent state.

Rationale:

• User Control: Advanced filters allow users to find relevant tickets quickly
• Performance: Database-level filtering reduces client-side processing
• State Persistence: Filter selections persist across page refreshes
• Progressive Enhancement: Basic filters always visible, advanced filters expandable

Implementation Details:
