Overview (Problem + Context)

  • Students used fragmented tools for notes, planning, and practice tests.
  • Existing study apps lacked personalization and feedback loops tied to performance.
  • The objective was to create a single workflow that improves consistency and confidence.

My Role + Responsibilities

  • Scoped MVP, authored product requirements, and prioritized feature rollout.
  • Implemented backend services, prompt orchestration, and front-end interfaces.
  • Defined instrumentation events to measure adoption and learning behavior.

Approach

  • Interviewed student users to identify high-friction points in revision routines.
  • Implemented retrieval pipeline over uploaded class notes and syllabus content.
  • Generated adaptive quizzes based on confidence and historical accuracy.
  • Added spaced-review reminders and progress checkpoints to support long-term retention.

Implementation Details (Stack + Architecture Choices)

  • Built application with Next.js App Router and server actions for streamlined data mutations.
  • Used PostgreSQL and Prisma for user progress, quiz history, and content indexing.
  • Integrated OpenAI API for summarization, question generation, and conversational tutoring.
  • Structured prompts for deterministic output format to support UI reliability.

Results (Metrics + Outcomes)

  • Reached 37% week-4 retention during pilot with university students.
  • Increased average weekly study session count from 2.1 to 3.8.
  • User feedback highlighted stronger confidence before exams and better topic prioritization.

What I’d Do Next (Reflection)

  • Add offline mode and sync to support intermittent connectivity.
  • Introduce instructor dashboards for cohort-level learning insights.
  • Expand personalization with mastery models and confidence calibration.
