Legacy System Modernization
Updating working systems with APIs and modern interfaces without rebuilding them from scratch.
Many businesses rely on a system that has run for years and holds their data and way of working, but has become hard to change, does not work on phones, or cannot talk to newer systems. Rebuilding it from scratch is expensive and risky, because the old system carries details that were never written down.
We start by studying the existing system: its database, the processes it performs, and the pain points its users face. We then propose a phased plan that keeps the system running throughout: adding an API so it can connect to an app or website, building a modern interface on top of the same data, or gradually moving parts of it to newer technology.
Each phase is tested on a staging copy before it goes live, with a backup and a rollback plan, so your work does not stop and your data is not lost. We document what we learn about the system along the way, making it easier for any team to work on later.
