English Master Pro

A production-ready, subscription-based educational platform designed to help users improve their English vocabulary and grammar through structured learning, personalized revision, practice drills, and timed assessments.

Built using Python, Flask, SQL, Firebase Authentication, and Firebase Realtime Database, the platform combines learning tools, progress tracking, payment processing, and role-based content management into a single web application. The system manages a vocabulary database of over 4,800 words, supports more than 100,000 vocabulary questions and 50,000 grammar questions, and provides separate workflows for learners, maintainers, and administrators.

Project Overview

English Master Pro was developed as a comprehensive learning platform that combines vocabulary acquisition, grammar practice, examination systems, progress tracking, subscription management, and educational content administration.

The application provides multiple ways for users to study and assess their knowledge, ranging from dictionary-based learning and randomized study sessions to configurable drills and timed examinations. Beyond the learner-facing features, the platform includes moderation and auditing tools that allow maintainers and administrators to continuously review and improve educational content.

The project represents the integration of many areas of web development, including frontend design, backend architecture, database management, authentication systems, payment processing, access control, and large-scale educational content management.
