Software Developer in London, United Kingdom

I'm the author and maintainer of this project. Since its creation in 2015, it has become the go-to place for in-app purchases on iOS. It is now used on thousands of apps.

To keep up with the growth of this project I have:
- Added extensive unit tests
- Added code linting
- Enabled CI integration
- Kept an up to date changelog
- Standardised and streamlined contributions 
- Adopted Gitflow

All of these things helped grow the project across multiple platforms and Swift language migrations.

I built this app to raise awareness about climate change and help individuals reduce their carbon footprint.

FEATURES:
• Keep track of your daily meals and journeys.
• View your CO2 emissions from food and transport.
• Get daily reports about your carbon footprint, with personalized suggestions to live more sustainably.
• Share your daily reports with family and friends, and on social media.
• Compare your CO2 emissions between different days, and see historical trends and statistics.
• Learn about CO2 emissions and the impact of food and transportation on the environment.
• Receive daily reminders to enter your meals and journeys (opt-in).
• Offline mode: Eco Buddy works anytime, anywhere - even without Internet connection.
• Fully automated iCloud syncing: Your data is stored safely and synced across all your iOS devices - no sign up needed.

The app is built in Swift, using Realm database and CloudKit for backup and syncing.

AcceptanceMark is the ideal tool to write Fitnesse-style acceptance tests that integrate seamlessly with XCTest:

- Write your tests inputs and expected values in markdown tables.

- Write test runners to evaluate the system under test with the given inputs.
- Run the chosen test target (Unit Tests supported, UI Tests will be supported) and get a test report.
