My experience

2018 - 2019   freelance
Android developer Good Energy.
Working remotely as part of a small team together with iOS developers, testers and a UX/UI designer we replaced a legacy app. We replaced Java with Kotlin and implemented an MVP architecture. I also set up PR (BitBucket) and CI (Bitrise) processes, including running automated UI tests on CI (Cucumber and Appium). The app used extensive communication with a number of backend servers (using Retrofit and OkHttp), and custom UI controls.
Java, Kotlin, Mvp, Dagger, Rxjava, Mockk, Appium

2018 - 2018   freelance
Android developer Dyson.
Part of a close team of Android, iOS and cloud developers, testers, UI designers and scrum facilitators. Adding new features to the Dyson Link app to support new products. The app uses MVVM architecture, and multiple modules and flavours. The development cycle is supported by the Atlassian suite (Jira, Bamboo, Stash, Hipchat). Hardware interaction used Bluetooth Low Energy at characteristic level and MQTT.
Java, Kotlin, Dagger, Rxjava, MVVM, Data binding, Mockito, Robolectric

2017 - 2017   freelance
Android developer and tester Xing AG.
Worked within a large distributed team, responsible for the re-development of a major section of the client’s app using strict MVP architecture. Also ported existing Cucumber (Calabash) tests from the iOS app to Android. Extensive use of the back-end cloud API using background tasks. Thorough unit test coverage of the logic (presenter) layer using Mockito.
Java, Kotlin, Mvp, Dagger, Rxjava, Mockito, Cucumber, Calabash

Geoffs reviews

Experienced Android developer, initially for short term project, but likely to lead to further projects.

Very knowledgeable and excellent communication. I would highly recommend Geoff for all aspects of Android Development.

Cross-platform mobile developer to build out an MVP, 2-3 months-ish work.
8 months ago

Geoff suggested a different way of working from our original proposal, which worked out a little quicker for the core functionality we actually needed now. We'll happily work with him again when we build out the remainder of our product.
