The Challenge

Atlas needed to modernize a monolithic core with weekly outages, batch-only ledgers, and slow product velocity — without disrupting 2M customers.

Our Approach

  • Strangler-fig migration decomposing the monolith into 24 event-driven microservices
  • Real-time ledger on Kafka with strong consistency and full audit trails
  • Zero-trust security architecture with continuous compliance and SOC2 evidence
  • Blue/green deploys with progressive rollout across regions
