Rebuilding an app its users would never notice had changed
Montag · Agricultural equipment
- The problem
- Their equipment calculator app had been left behind by the developer who originally built it, with nobody maintaining it. It needed a complete rebuild. But the people opening it in the field every day didn't need a new experience — they needed the one they already knew to keep working.
- What I built
- I worked back through the original app's interface and calculations, then rebuilt it from scratch on a modern cross-platform framework. Same layout, same numbers, same muscle memory — now one codebase covering both iOS and Android instead of a dead end.
- The result
- A faster, maintainable app that existing users picked up without retraining, and a codebase that can actually be updated as the equipment line changes.
