The Challenge
Houston Property Services was struggling with manual quote generation for property maintenance services. Their process involved:
- Sales representatives manually calculating prices
- 2-3 day turnaround for complex quotes
- Inconsistent pricing across team members
- Lost opportunities due to slow response times
The company needed a solution that could:
- Generate accurate quotes instantly
- Maintain pricing consistency
- Handle complex property requirements
- Scale with business growth
The Solution
I architected and built a comprehensive quote generation platform that leverages AI to analyze property details and generate accurate, consistent quotes in real-time. The system transforms how the company operates, turning a multi-day process into a matter of seconds.

Technical Deep Dive
AI Pricing Algorithm
The quote generation engine uses multiple factors:
interface QuoteFactors {
propertySize: number;
propertyType: 'residential' | 'commercial';
serviceType: ServiceType[];
urgency: 'standard' | 'rush' | 'emergency';
seasonalAdjustment: number;
historicalData: PricingHistory[];
}
async function generateQuote(factors: QuoteFactors): Promise<Quote> {
// Base pricing calculation
const basePrice = calculateBasePrice(factors);
// AI adjustment based on historical data
const aiAdjustment = await ai.predictOptimalPrice({
...factors,
basePrice,
marketConditions: await getMarketData()
});
// Apply business rules
const finalPrice = applyBusinessRules(basePrice + aiAdjustment);
return {
price: finalPrice,
breakdown: generateBreakdown(factors),
validUntil: addDays(new Date(), 30)
};
}Real-time Updates
Implemented WebSocket connections for live updates:
// Real-time quote status updates
socket.on('quoteUpdate', (quoteId: string) => {
// Update UI without page refresh
updateQuoteStatus(quoteId);
// Show notification
showNotification('Your quote has been updated!');
});Security Implementation
- Row Level Security (RLS) in Supabase
- API rate limiting with Redis
- Input validation at every layer
- Encrypted file uploads
- MFA for admin accounts
