Problem

A video-stream management product had grown into a tangled PHP code base. The team wanted to migrate to a unit-tested Java back-end and a modern React front-end without a big-bang rewrite.

What I did

  • Built front-end features in React against the existing API surface.
  • Rebuilt legacy PHP subsystems in modern, unit-tested Java.
  • Designed synchronization layers between the legacy and modern back-ends so both could run side by side while features migrated.
  • Worked with test-runners — sitting with operators using the product in real conditions — and folded their feedback directly back into the development cycle.

Outcome

Legacy subsystems were progressively replaced under a stable user-facing front-end, with the React side picking up features as the back-end moved over.
