Overview

LLMs change every few months. Architecture should not. In this session, participants will be exposed to real-world architectural patterns, scaling strategies and hard-earned lessons from building modular, multi-LLM virtual assistant platforms. Whether you’re launching your first assistant or scaling an existing platform, this session offers field-tested strategies and actionable insights—with space for shared learning and peer exchange. Whether you’re launching your first assistant or scaling to thousands of concurrent users, this session provides proven architectural guidance and implementation insights. We will explore:
  • How to design backend systems that remain flexible as LLMs evolve
  • Why separating prompts from code is critical for long-term maintainability
  • Practical RAG architectures using vector databases such as Pinecone
  • Orchestration strategies with LangChain and alternative approaches
  • Observability and prompt performance analytics with Phoenix
  • Integrating STT/TTS for full voice-enabled experiences
  • Managing cost, latency, drift and production reliability
This is not a theoretical overview — it’s a practical walkthrough of what works (and what breaks) when GenAI systems meet real users and enterprise requirements.

Who Should Attend

Developers, Architects, Engineering Managers and Technical Leaders interested in understanding how to build scalable and flexible backend architectures for AI-powered applications.

Prerequisites

Course Contents

Virtual Assistant Backend Architecture: The Essentials
  • High-level flow of a GenAI-powered virtual assistant
  • Core components: Frontend (chat/web/voice), Backend API, LLM orchestrator, RAG server, STT/TTS layer, and analytics
  • Example Phoenix server role in managing the state and flow
Separation of Code and Prompts
  • Benefits of decoupling logic from prompt design
  • Using templating and versioning for prompts
  • Integration strategies for storing prompts in external services (e.g., DBs or repos)
Supporting Multiple LLMs: Abstraction and Flexibility
  • How to switch between models (e.g., OpenAI, Anthropic, Mistral, custom models)
  • Building modular backends to support pluggable LLMs
LLM Communication: Langchain & Alternatives
  • Introduction to Langchain and how it simplifies agent-based architectures
  • Examples of chaining steps, memory, and tools
  • Comparison with other orchestration layers and custom implementations
Retrieval-Augmented Generation (RAG): Core Patterns
  • What RAG is and why it matters
  • Using vector stores like Pinecone to enhance responses
  • Workflow: Ingest – Embed – Store – Retrieve – Inject
Prompt Engineering Analytics: Phoenix + Beyond
  • Importance of understanding prompt performance over time
  • Using Phoenix for experiment tracking, prompt scoring, and observability
  • Visualization of token usage, LLM latency, output drift
   What Attendees Can Expect:
  • A suggested proven architecture for building a robust Virtual Assistant platform
  • Guidance on designing a flexible system that supports multiple LLMs and can adapt to LLM replacements
  • Practical insights into monitoring and tuning both LLMs and prompt strategies
  • Real-world lessons and best practices from experienced experts actively developing and deploying GenAI systems
