A UK-based B2B SaaS company offering customer feedback and analytics tools faced critical backend performance issues. Their application, built years ago with outdated vanilla PHP and minimal framework structure, became a bottleneck as their user base grew.
They reached out to Code Elevator for a complete backend migration to Laravel, aiming to modernize their stack, enhance maintainability, and prepare the platform for scale.
- Legacy PHP codebase: Difficult to scale, debug, or test
- Slow feature rollout due to lack of framework support
- Backend performance lagged under concurrent user loads
- Poor API response times affecting front-end speed
- Inconsistent code standards across modules
- The goal was to migrate to Laravel while minimizing downtime, ensuring continuity of user data, and enabling faster development cycles moving forward.
Code Elevator provided a dedicated Laravel team to lead the end-to-end migration.
Team Composition:
- 3 Laravel Developers
- 1 DevOps Engineer
- 1 QA Engineer
- 1 Technical Project Manager
