This article is written for GKE turns 10 hackathon

With BoutiqueAI Assistant, I built a complete conversational shopping system powered by Google ADK, Gemini LLM (Function Calling), and FastAPI — all integrated with 9 gRPC microservices from Google’s Online Boutique demo app.

This post walks through the architecture, features, demo flow, and how you can try it locally or on GKE.

Architecture Overview

Data Flow:

User Request → React Frontend → FastAPI Backend
AI Processing → Google ADK Agent → Gemini API
Microservice Calls → gRPC Client → 9 Microservices
Response Assembly → Backend → Frontend → User

Communication Patterns:

Frontend ↔ Backend → REST (JSON)
Backend ↔ AI → Google ADK + Gemini API
Backend ↔ Microservices → gRPC (Protocol Buffers)
Infra → Kubernetes service discovery

Key Features

AI Shopping Assistant

Natural language search
Price filtering (“Show me gifts under $50”)
Intelligent recommendations (“You may also like…”)
Product ads (contextual, clickable)
Chat interface for full shopping flow

E-Commerce Capabilities

Browse/search catalog
Add/remove from cart
Checkout & payment (test mode)
Order confirmation with product images
Currency conversion
Shipping quotes & processing
Email confirmations

Modern UI/UX

Responsive React + Tailwind CSS
Smooth animations (Framer Motion)
Product cards with “Add to Cart”
Polished order confirmation screens

Product Demo Flow

Welcome Page → clean chat interface
Product Search → conversational queries with product cards
Recommendations & Ads → context-aware suggestions
Add to Cart & View Cart → visual cart with totals
Checkout → simulated payment + order email
Order Confirmation → professional confirmation with product details

Tech Stack

Frontend

React 18, Tailwind CSS, Framer Motion
Heroicons, ReactMarkdown, Axios

Backend

Python 3.9+, FastAPI, Uvicorn
Google ADK (Agent Development Kit)
gRPC + Pydantic

Microservices (from Online Boutique)

Product Catalog (3550)
Cart (7070)
Recommendation (8080)
Shipping (50052)
Currency (7000)
Payment (50051)
Email (5000)
Checkout (5050)
Ads (9555)

Quick Start

1. Clone & Setup

git clone https://github.com/arjunprabhulal/ai-botique-assit
cd botiq-ai-assist

# Backend
pip install -r requirements.txt

# Frontend
cd frontend && npm install && cd ..

2. Start Everything (Recommended)

utilities/start_local_dev.sh

This will:

Port-forward gRPC services
Start backend (FastAPI + AI agent)
Start frontend (React)

Access the app:

Frontend → http://localhost:3000
Backend API → http://localhost:8000
API Docs → http://localhost:8000/docs

3. Stop Services

utilities/stop_local_dev.sh

AI Agent Functions

The Google ADK agent exposes gRPC functions like:

Product Catalog → list_products, search_products, get_product
Cart → add_item_to_cart, get_cart, empty_cart
Order Processing → place_order, initiate_checkout
Shipping & Payment → get_shipping_quote, ship_order, charge_card
Extras → list_recommendations, get_ads, convert_currency, send_order_confirmation

Deploying to GKE

For production deployment:

export PROJECT_ID="your-project-id"
utilities/prepare_deploy.sh```
{% endraw %}


This script:

- Switches to Kubernetes mode  
- Builds & pushes Docker images ({% raw %}`linux/amd64`{% endraw %})  
- Deploys to GKE with rolling updates  
- Prints external access URL  


## For production deployment:
{% raw %}


```bash
export PROJECT_ID="your-project-id"
utilities/prepare_deploy.sh

Dev Workflow

Local Dev:

utilities/start_local_dev.sh  
utilities/stop_local_dev.sh

Deployment:

export PROJECT_ID="your-project-id"
utilities/prepare_deploy.sh

Switch Environments:

utilities/toggle_grpc_urls.sh local   # local mode
utilities/toggle_grpc_urls.sh k8s     # k8s mode

BrightData MCP Platform- AI Search and Scrape using Google ADK and Gemini

This is a submission for the Bright Data AI Web Access Hackathon

What I Built

I built a professional-grade web scraping and data extraction platform that combines BrightData's MCP (Model Context Protocol) tools with Google's Agent Development Kit (ADK) and Gemini 2.0 Flash AI. This platform provides real-time access to web data through 50+ specialized scraping tools, all powered by BrightData's enterprise proxy network.

🔒 API: https://brightdata-mcp.aicloudlab.dev/api/
🔒 Docs: https://brightdata-mcp.aicloudlab.dev/docs
🔒 Health: https://brightdata-mcp.aicloudlab.dev/health

🎯 Problem Solved:

Traditional AI systems are limited by static training data and can't access real-time web information. My platform solves this by:

Real-time data extraction from any website
Intelligent web scraping with AI-powered analysis
Professional-grade infrastructure with enterprise proxies
Multi-platform data access (e-commerce, social media, news, business intelligence)

🛠️ Key Features:

🤖 Google Gemini 2.0 Flash AI for intelligent data processing
🌐 50+ BrightData MCP Tools for comprehensive web access
