Laravel Legacy System Refactoring.
Resuscitating aging enterprise monolithic applications. I scale B2B systems, eliminate N+1 query bottlenecks, and enforce SOLID principles for zero-friction operations.
The Challenge of Legacy B2B Systems
Many enterprise-scale Laravel applications that began operating years ago suffer from performance degradation as their databases grow. Symptoms include business logic leaking into controllers (Fat Controllers), lethargic response times due to N+1 queries in the Eloquent ORM, and a severe lack of test coverage.
The Strangler Fig Migration Pattern
Instead of attempting a high-risk "Big Bang Rewrite" (which notoriously fails), I slowly strangle the legacy codebase. New features are built strictly using modern architectural standards (Service Classes, Actions, Repositories) running alongside legacy code until the legacy system can be safely retired with zero downtime.
Reconfiguring Foreign Key constraints and cascade data integrity to eliminate orphan records.
Wrapping legacy behavior in characterization tests to guarantee structural changes never break edge cases.
