Legacy System Modernisation
A staged roadmap to modernise a legacy system without a risky big-bang rewrite.
Overview
A staged roadmap to modernise a legacy system without a risky big-bang rewrite. I mapped the legacy system, identified the highest-value modules to modernise first, and designed a staged strangler-pattern roadmap that delivers value incrementally while keeping the lights on. Built with Modernisation, Laravel, Architecture, this consulting project was delivered for a client in USA and designed for reliability, a clean user experience and long-term maintainability — so it keeps delivering value well after launch.
The challenge
A business depended on an ageing system that was costly to maintain and hard to change, but a full rewrite felt too risky.
What I built
