• Leading a team of 6 Flutter engineers (while overseeing another 2 teams) where my role includes being hands-on but also being a force multiplier & ensuring the quality of the apps shipped every 2 weeks.
• Writing and reviewing RFCs for new features & big refactoring tasks plus mentoring peers on how to write and review them.
• Released the first Flutter app at DH in 6 months on both Android and iOS in multiple markets using a single codebase where each market had its own features, theme and localisation using flavors on Android & schemes on iOS.
• Built CI/CD pipelines using Fastlane, Bitrise & Github Actions for running tests on PRs & releasing the apps to the AppStore, PlayStore and HuaweiAppGallery.
• Migrated our Flutter app with 105k lines of code to sound-null-safety in 11 months without impacting our release cycle.
• Worked with flutter_bloc for state management, get_it for dependency injection, dio for consuming REST APIs, graphql_flutter for consuming Shopify?s Storefront GraphQL API and stream_chat_flutter for integrating a real-time chat module in the app.
• Wrote unit tests using mockito, mocktail & bloc_test, widget tests for the core design system & integration tests for the apps.
• Automated repetitive dev tasks such as setting up a feature adhering to clean architecture by using mason and freezed. 

Big win for the business: The mindset within DH has changed to ?Flutter First? after witnessing a decreased time to market, native app performance and 100% feature parity between Android & iOS. Almost every new app is now being built with Flutter.

Before this Flutter project, I worked on the Foodpanda Android app (Native Android development with Kotlin/Java):

• Reduced Google API costs by 66% ($50k) by working closely with the backend team to improve our caching mechanism.
• Built the app?s design system from scratch with complex views with customer delight and developer productivity as the goal.
• Built and presented a ?Lite version? of the Foodpanda app built with Flutter - Watch here. (Internal hackathon project)
• Mentored 2 QA engineers to help them learn Kotlin and write automation tests so that they could upskill. 1 of them
• successfully transitioned to a developer role after 8 months.

Note: I joined as a Software Engineer in Oct 2018; got promoted to Senior Software Engineer in Jan 2021; got promoted to Staff Software Engineer in Nov 2021.
