The engineering overhaul delivered immediate, quantifiable gains. GraphQL eliminated data over-fetching across our mobile network, reducing payload weights by up to 70%. We achieved near-zero error rates in pipeline ingestion by automating customer profile sanitization through LangChain and GPT workflows. Kafka buffers and Optimistic Concurrency Control eliminated the database performance degradation we'd experienced during peak hours. Most critically, we now capture 100% accurate, live financial telemetry that tracks exact customer segmentation and ARPU in real time—something our legacy Micros-Fidelio system couldn't support.

The results spoke for themselves: we reduced our CPA to nearly zero for future acquisitions, increased sales by 32%, and improved ARPU across multiple customers. Their strategy also lowered our churn rate, driving a 74% increase in repeat users with higher average order value.
