A global organization initiated a transformation program to modernize its customer engagement systems. The objective was to replace a legacy CRM workflow with a new customer engagement platform while improving engineering practices, release speed, and long-term scalability.

The engagement began in October 2024 and ran for over a year. The project was initially scoped for 20 developers and 8–9 QA engineers, but was successfully delivered by a team of 9 developers and 2 QA engineers, demonstrating a significantly more efficient delivery model.

The organization faced several technical and operational challenges:

• Migration from a legacy CRM workflow to a new customer engagement platform
• Legacy codebase built on Java 7
• Complex and fragmented system architecture
• Lack of centralized documentation
• Manual QA processes taking up to four weeks per release cycle
• Multiple regional branches causing code drift
• Limited automated testing and outdated APIs

Even the development environment posed challenges. Initial system setup took nearly a week due to outdated tooling and fragmented technical knowledge.

The engagement began with a discovery phase where engineers worked closely with the client’s technical teams to understand the architecture and operational workflows.

Key elements of the approach included:

• Pair programming with client engineers
• Collaborative code exploration
• Peer reviews and shared engineering practices
• Incremental ownership of system components
• Remote-first collaboration across distributed teams

Rather than simply executing assigned tasks, the team introduced modern engineering practices to improve delivery efficiency and software quality.

CRM Platform Migration

Customer workflows were successfully migrated from the legacy CRM integration model to a modern customer engagement platform while maintaining operational continuity.

Accelerated Delivery

The first major release originally scheduled for March 2025 was delivered in January 2025, two months ahead of schedule.

Engineering Practice Improvements

The team introduced:

• Pair programming
• Peer code reviews
• Collaborative solution design
• Test-driven development for newly built services

These practices improved quality and delivery speed despite the legacy environment.

Release Automation Strategy

Manual QA cycles lasting up to four weeks were identified as a key bottleneck. The team recommended introducing automated testing and continuous integration pipelines to significantly reduce release timelines.

Branch Unification Strategy

Multiple regional branches had created duplication and maintenance overhead. The team recommended a feature-toggle based architecture to support regional differences within a unified codebase.

Technology Modernization

Legacy services were originally built on Java 7. As part of the modernization effort:

• Legacy services were upgraded toward Java 17
• Newly built services were implemented using Java 21

This ensured long-term compatibility with modern development ecosystems.

Beyond the CRM migration, the program helped the organization:

• Modernize engineering practices
• Introduce automation-driven delivery workflows
• Reduce technical debt
• Prepare the platform for long-term scalability
