OPIc mock-test and AI feedback app
An OPIc learning app for recording answers, submitting them and reviewing scores and feedback. I handled planning, Flutter development and both store releases, including answer submission and lifecycle-aware notifications.
Screens
From recording to feedback
Users read a question, record an answer and submit it. I implemented conversion to the submission format, upload, and the flow for viewing assessment results and feedback.
Development and release
I built the app with Clean Architecture, integrated social login and in-app payments, separated development, staging and production environments, and released it on iOS and Android.
Notifications across app states
I distinguished foreground, background and terminated-state handling. Deep links take users from a notification to the relevant screen, connecting actions outside the app to the learning flow.
