A legacy banking back-office becomes a mobile app.
A bank's services lived behind a legacy core — secure, but with no modern, multi-language app its retail customers could use day to day.
A Flutter app on the existing banking stack: challenge-response authentication, transaction signing, and multi-language delivery, scoped in phases against a live rollout.
A customer-facing app that meets the institution's security bar and ships to a real rollout — transformation without ripping out the core.
