01 / CONTEXT & CONTRIBUTION
The problem.
My part in it.
Background
- Learners needed a path from Hangul and a first sentence to everyday writing and TOPIK practice.
- A score alone did not explain how to revise or what to practice next.
- Different goals, languages and interrupted submissions required distinct feedback and reliable progress recovery.
Objective
- Connect goal-based practice, task-specific feedback, rewriting and spaced review.
- Preserve drafts and progress when learners switch goals or return to the app.
My role
- Independently planned the learning experience, content and product; developed with AI and handled QA.
- Implemented task-specific assessment, five-language feedback, submission recovery and learning-record sync; released on iOS and Android.

How it connects.
Processing / data flowIteration / feedbackService / environment boundary
Different writing, different feedback.
Everyday writing focuses on meaning and natural expression. TOPIK uses question-specific paths: blanks for 51–52 and a four-axis rubric for longer writing. Separate scoring from localized explanations in the rubric path.
Make feedback usable again.
Connect inline corrections to rewriting, learner-selected expressions and spaced review. Recover interrupted submissions and preserve account-linked learning records; keep drafts and newly written practice sentences on the device.
