Search Performance
Property search must return results in under 500ms with complex filtering, sorting, and geo-spatial queries across millions of listings.
Serverless & Lambda Consulting
AWS Serverless for Real Estate & PropTech
We build serverless real estate platforms on AWS that handle property search, listing management, and buyer notifications — scaling automatically with market activity and costing nothing during off-hours.
- An event arrives — API, queue, or schedule.
- A function handles one unit of work.
- Integration is the bus and the store, not a hidden hop.
- Traces and alarms are in the same change as the function.
- Deploys stop on the pipeline check, not after customers see it.
- Capacity follows load; idle time is not a fleet you pay for.
Key Challenges We Solve
Real-Time Listing Updates
MLS feeds push thousands of listing changes per hour — new listings, price changes, and status updates must be reflected immediately.
Market-Driven Traffic
Real estate traffic varies dramatically with interest rate changes, seasonal patterns, and market events.
Image Delivery
Property listings average 20-30 images each. Serving millions of high-quality images efficiently requires smart caching and optimization.
Our Approach
Serverless Search API
API Gateway + Lambda + OpenSearch for property search with geo-spatial queries, faceted filtering, and relevance scoring. ElastiCache for sub-50ms cached results.
Event-Driven Listing Pipeline
Lambda functions process MLS feeds in real time, normalize data, update search indexes, and trigger saved search notifications via EventBridge + SES.
Optimized Image Delivery
S3 for storage with Lambda@Edge for on-the-fly image resizing, WebP conversion, and CloudFront caching for fast global delivery.
Frequently Asked Questions
Can serverless handle millions of property searches?
Yes. API Gateway scales to thousands of requests per second, Lambda handles search logic, and OpenSearch provides sub-second property search across millions of listings. ElastiCache caches popular searches for sub-50ms response times.
How do you handle real-time MLS updates?
Lambda functions poll MLS APIs or receive webhooks for listing changes. Updates flow through an event pipeline that updates DynamoDB, OpenSearch indexes, and triggers saved search alerts — all within minutes of MLS publication.
What does a serverless real estate platform cost?
A mid-size real estate platform with 500K listings and 1M monthly searches typically costs $2,000-$5,000/month on serverless. Costs scale linearly with searches and listing volume, and drop during off-peak months.
