Legacy Modernization
Without Business Interruption
Your system is running, but every change feels like surgery on a living patient? I modernize legacy systems step by step - without big bang, without business standstill.
Signs Your System Needs Modernization
These symptoms indicate that action is required
Code Areas Nobody Touches
"Don't touch that, nobody understands it anymore." Classic symptom of technical debt that has gotten out of control.
PHP 7.x or Older
PHP 7.4 reached EOL in November 2022. Security updates are no longer coming. Migration is mandatory.
Outdated Frameworks
Symfony 3, Laravel 5, Shopware 5 - all without active support. Each new feature becomes a security risk.
Deployment as "Event"
When deployments require a meeting, something is wrong. Modern systems deploy 10x daily without drama.
My Approach: Strangler Fig Pattern
Step-by-step replacement instead of risky big bang
Analysis & Mapping
Understand the existing system. Identify dependencies, find pain points, create migration roadmap.
Build Parallel
New components are built alongside the old system. Feature by feature, module by module.
Gradual Cutover
Traffic is gradually redirected to new components. Old parts are shut down when no longer needed.
Decommission
After successful migration, old system is cleanly shut down. Documentation updated, team trained.
