Deployment speed

Challenge

A HIPAA-compliant healthcare SaaS running on aging on-premise infrastructure needed to migrate to the cloud without any downtime. Their monolithic architecture made scaling impossible and deployments took weeks.

Solution

We designed a phased migration to AWS with a microservices refactor. Implemented Kubernetes for orchestration, Terraform for IaC, and a full CI/CD pipeline. Zero-downtime migration over 8 weeks with HIPAA compliance maintained throughout.

Results

  • Infrastructure costs reduced by 60% ($200K/year)
  • Deployments went from 2 weeks to 15 minutes
  • Zero downtime during migration
  • Auto-scaling handles 10x traffic spikes

"Lexora's team delivered ahead of schedule and under budget. The migration was seamless — our users didn't notice a thing, but our engineering team noticed immediately. Everything is faster."

8 weeks
Delivery time

Challenge

A growing fintech needed real-time fraud detection and analytics across 50M+ daily transactions. Their batch-processing system had 4-hour delays, allowing fraud to go undetected.

Solution

Built a streaming architecture using Kafka, Apache Flink, and ClickHouse. Implemented ML-based anomaly detection running in real-time. Deployed on Kubernetes with auto-scaling.

Results

  • Fraud detection latency reduced from 4 hours to under 100ms
  • $1.2M in fraud prevented in the first quarter
  • Real-time dashboards for the entire executive team

"The Lexora team built in 8 weeks what we estimated would take 6 months internally. The real-time pipeline they built is now a core competitive advantage for us."
