Engineering challenges

What made it hard — and how we approached it

The problems
01

Full-Stack Development Coordination

Coordinating frontend and backend development teams to ensure seamless integration and consistent functionality across the platform.

02

Appointment Booking System Complexity

Designing a flexible appointment booking system that could accommodate various business types, time zones, and availability patterns.

03

Product Recommendation Engine Accuracy

Creating intelligent recommendation algorithms that could effectively suggest relevant products based on limited user interaction data.

04

CRM Integration Standardization

Developing a standardized approach to integrate with diverse CRM systems while maintaining data consistency and synchronization.

Our approach

Integrated Development Methodology

Implemented a collaborative development process where frontend and backend teams worked in synchronized sprints with shared planning and review sessions.

Component-Based Architecture

Built the platform using reusable components that could be assembled in different configurations to meet various business requirements and use cases.

AI Conversation Flow Design

Designed sophisticated conversation flows that could intelligently guide customers through appointment booking and product selection processes.

Universal CRM Adapter Pattern

Developed an adapter pattern implementation that standardized data exchange with various CRM systems through a unified API interface.

Performance Optimization Framework

Implemented comprehensive performance monitoring and optimization strategies to ensure real-time responsiveness across all user interactions.

Technical architecture

Embeddable AI sales agent with a GraphQL core and CRM adapters

The Elefant is an AI sales assistant that businesses drop into their websites to chat with visitors, recommend products, book appointments and push leads into their CRM. It runs as a Next.js and React front end backed by a Node.js and Express GraphQL API over PostgreSQL, with a conversation orchestrator that calls a large language model and a set of tool services for booking, recommendations and CRM sync. A modular monolith with clear service boundaries suited a fast-moving product that had to serve many small businesses from one deployment.

Clients

A lightweight embeddable chat widget on customer websites, plus a Next.js admin console where businesses train the assistant and review leads.

  • Embeddable chat widget
  • Next.js admin console
  • Business onboarding flows
  • Mobile apps for members

API & edge

A single GraphQL endpoint on Node.js and Express authenticates widgets by site key and operators by session, and streams chat responses.

  • GraphQL API gateway
  • Site-key widget auth
  • Operator session auth
  • Streaming chat responses

Core services

A conversation orchestrator manages each visitor dialogue and invokes tools: appointment booking, product recommendation and CRM update.

  • Conversation orchestrator
  • Appointment booking service
  • Recommendation engine
  • Universal CRM adapter
  • Lead capture and scoring

Data

PostgreSQL holds tenants, conversations, products, bookings and leads; a vector index stores embedded business knowledge for retrieval.

  • PostgreSQL tenant and lead store
  • Conversation history
  • Product catalogue tables
  • Vector knowledge index

AI / integrations

A large language model drives dialogue over retrieved business knowledge, while adapters connect to CRMs, calendars and Razorpay for payments.

  • Large language model
  • Retrieval over business content
  • CRM connectors
  • Calendar availability sync
  • Razorpay payments

Infrastructure & delivery

Cloud-hosted Node services behind a CDN that serves the widget script globally, with performance monitoring on every chat turn.

  • CDN-delivered widget script
  • Cloud container hosting
  • Performance monitoring
  • CI/CD pipeline
Request lifecycle
  1. 01

    A business pastes the widget script into its site; the admin console ingests site pages and product data into the vector knowledge index.

  2. 02

    A visitor opens the chat; the widget calls the GraphQL gateway with the site key and the orchestrator loads tenant settings.

  3. 03

    The orchestrator retrieves relevant business knowledge, prompts the language model, and streams the reply back to the widget.

  4. 04

    When the visitor wants a product or a slot, the model invokes the recommendation or booking tool, which reads availability from PostgreSQL.

  5. 05

    A confirmed booking or qualified lead is written to PostgreSQL and pushed through the CRM adapter to the business's CRM.

  6. 06

    Payments, where needed, are collected through Razorpay, and the admin console shows conversations, leads and conversion analytics.

Key decisions

GraphQL as the single API surface

The widget, admin console and mobile apps needed different slices of the same data; one typed GraphQL schema avoided a sprawl of REST endpoints across frontend and backend teams.

Tool-calling orchestrator around the model

Booking and recommendations need deterministic business logic; keeping them as explicit tools the model invokes kept the LLM conversational while real actions ran in tested code.

Universal CRM adapter pattern

Every client used a different CRM; normalising lead and contact exchange behind one adapter interface let the team add CRMs without touching the conversation flow.

Component-based, multi-tenant monolith

Serving dozens of small businesses from one Node.js deployment with tenant isolation in PostgreSQL was cheaper and faster to iterate than per-client infrastructure at this stage.

Security & compliance
  • Widget requests authenticated by per-site keys bound to allowed origins; operators use session-based auth with role scopes.
  • Strict tenant isolation in PostgreSQL so one business's conversations, leads and knowledge never leak into another's assistant.
  • CRM and calendar credentials stored encrypted and accessed only through the adapter layer.
  • Payments handled by Razorpay so card data never touches application servers.
  • Prompt and retrieval guardrails restrict the assistant to the tenant's own content and approved actions.
