DEPLOYMENTS
Technical solutions engineered for scale. Real problems. Measured results.
CASE STUDY 01
The SaaS Integration
The Bottleneck
Client lost ~23% of inbound leads during ad campaigns because their CRM webhook endpoint timed out (504 Gateway Timeouts) under concurrent load. Direct integration couldn't handle the concurrency.
The Deployment
Architected an asynchronous buffering layer. Replaced direct webhook connection with a high-throughput Redis-backed queue (via BullMQ). Configured n8n as a controlled consumer to process leads at a rate the CRM could handle (rate-limiting), with automatic retry logic for failed syncs.
The Result
100% lead capture during Black Friday traffic. The 'buffer' absorbed the spike, and the CRM processed leads sequentially without crashing. CPA stabilized as every click was actually attributed.
CASE STUDY 02
Real Estate Lead Scoring
The Bottleneck
Sales team wasted 30+ hours/week calling 'tire kickers'. Universal lead forms treated a curious browser the same as a ready-to-buy investor. High-value prospects were getting buried.
The Deployment
Implemented a client-side heuristic scoring engine using Google Tag Manager. Assigned weighted points for 'high-intent' actions: Pricing Page Dwell (>45s), Map Interaction, and Staff Bio Views. Leads with Score < 40 were routed to email nurture; Score > 70 were pushed to CRM via API with a 'Hot Lead' tag.
The Result
Sales team efficiency skyrocketed. Call-to-Book ratio increased by 45% because they only engaged with users demonstrating high digital intent. Ad spend efficiency improved by feeding 'High Score' conversion events back to Meta pixel.
