LEGACY MODERNIZE

The challenge A ten-year-old PHP app was slow to change and risky to deploy, but the business could not afford downtime for a rewrite. What I built A screen-by-screen migration to React and Node on AWS, running old and new side by side behind the same routes until each part was ready to switch over. The result The whole product moved to the new stack with no outage, and releases went from monthly to several times a week.
