SkillBridge — AI-Powered Exam Prep for African High-School Students

A mobile app that turns a phone into a curriculum-aligned study partner. Designed for students in Ethiopia preparing for national exams, then expanded to high-schoolers across 20+ African countries.

Role: AI Software Engineer (backend) — AI tutor chatbot, exam-generation services, content APIs, and the backend that powers the Flutter clients on Android and iOS.

The problem

Most high-school students across Ethiopia and neighboring countries prepare for national exams with outdated printed material and little personalized feedback. Quality prep is concentrated in urban centers and priced out for most families.

What we built

• Curriculum-aligned notes. Structured study notes mapped to the national syllabus, served through a content API and rendered natively in the app.
• Mock exams. Generated and scored exams per subject, with explanations for every wrong answer.
• AI tutor chatbot. OpenAI-backed Q&A grounded in the course material, tuned for high-school reading level and the specific curriculum the student is enrolled in.
• Adaptive quizzes. Question difficulty shifts based on the student's running accuracy and weak topics, so revision sessions stay useful instead of getting easy or overwhelming.

Architecture

• Backend (Python). Content, exam, and chat services exposing REST endpoints consumed by the Flutter apps.
• AI layer. OpenAI API for the tutor chatbot and for generating exam variants, with prompt templates tied to the syllabus taxonomy.
• Mobile (Flutter). Single codebase shipped to both Play Store and App Store, optimized for low-bandwidth environments.

Outcome

• 1,000+ downloads in the first release cycle.
• Reach across 20+ African countries within the first months.
• A stable content pipeline the team can extend with new subjects without engineering work on every update.
