The Challenge

Aging Monolith Threatening Business Growth

A healthcare technology company's core platform—built 15 years ago—couldn't scale to meet growing demand. Feature development had slowed to a crawl, and the risk of critical failures increased monthly.

Key Pain Points

  • 6-month feature delivery cycles due to monolith complexity
  • Single point of failure threatening 99.9% SLA commitments
  • Only 2 engineers understood the legacy codebase deeply
  • Unable to adopt modern security and compliance requirements

Our Approach

16-Week Embedded Modernization Program

Our team embedded with their platform engineering group, systematically decomposing the monolith while ensuring zero disruption to production operations.

1

Assessment & Strategy

Weeks 1-3
  • Complete system archaeology and dependency mapping
  • Domain boundary identification using DDD principles
  • Strangler fig pattern strategy development
  • Risk mitigation and rollback planning
2

Incremental Extraction

Weeks 4-12
  • Service extraction with embedded pair programming
  • Continuous deployment with feature flags
  • Parallel running and validation
  • Progressive traffic migration
3

Completion & Capability Transfer

Weeks 13-16
  • Final service extraction and monolith retirement
  • Platform team training and certification
  • Operational playbooks and incident response
  • Independent operation validation

The Solution

Modern Microservices Platform with DevOps Excellence

A fully decomposed, cloud-native platform with CI/CD automation and a team equipped to continue the modernization journey.

Technologies Used

Kubernetes
Go
PostgreSQL
Redis
Terraform
ArgoCD

Key Deliverables

  • 12 extracted microservices from monolith
  • Kubernetes-based deployment platform
  • CI/CD pipeline with automated testing
  • Comprehensive monitoring and observability
"The embedded approach was transformative. Our team didn't just get a new platform—they gained the skills and confidence to own and evolve it independently."
