We develop custom iOS and Android applications using Kotlin, Swift, Objective-C and Java. Our approach means that overall, the application delivered is yours, and is completely scalable and testable.
Built to last, not just to ship
A native app is easy to start and hard to keep. The difference shows up a year in, when the feature you need next either drops into place or forces a rewrite. We build for that second year: clear boundaries between layers, tests that describe real behaviour, and a codebase a new engineer can read without a guided tour.
That means writing in the platform’s own language and idioms — Kotlin and Java on Android, Swift and Objective-C on iOS — rather than fighting a cross-platform abstraction to reach the APIs you actually need.
What we work on
- Custom iOS and Android applications, from first commit to store release
- Native development on iOS, Android, and Linux
- Integration with the web platforms and APIs that back the app
- Digitally integrated physical products, where the app is one part of a larger system
How we work
Test-driven development, continuous integration, and the practices of Extreme Programming are not add-ons here — they are how the work gets done. Every line is reviewed, tested, and owned by an experienced engineer.
Mark has led engineering for products used by millions, including apps recognized by the White House as a Champion of Change and a connected-home product ranked highest in customer satisfaction by J.D. Power, and has partnered with brands like Emerson and MLS club St. Louis CITY SC.
The code is yours
You own the result. No proprietary framework to license, no dependency on us to keep it running. If you bring the work in-house or hand it to another team, the codebase, the tests, and the build pipeline go with it.
