This project was a collaborative team effort completed as part of CSCE 247: Software Engineering. I served as Product Manager and also contributed significantly to Backend Development and UI Design. I played a substantial role (50%+ influence) in scoping product requirements, building backend logic, and designing the JavaFX interface. Contributions from other team members are acknowledged beneath the respective items.
OVERVIEW + Impact Metrics
Our challenge was to design and implement a Duolingo-inspired language learning platform from scratch, applying Agile methodology over the course of the semester. The app allows users to select a language, complete structured lessons, and track their progress through quizzes and dashboards.
Coordinated a 4-person Agile team across three sprints, retros, and weekly standups.
Shipped a functional MVP with 6+ features: user authentication, language selection, lesson modules, quizzes, progress tracking, and leaderboards.
Delivered a fully working demo at semester’s end, meeting 100% of sprint goals.

Backend Development
The backend was written in Java using object-oriented programming principles and software engineering practices (e.g., design patterns).
Key contributions:
Designed the system’s UML diagram to model core classes, interfaces, and data flows — providing the blueprint that guided backend development.
Built the progress persistence system with FileLoader, ensuring user data was saved/retrieved across sessions.
Developed Language and Lesson modules, using Factory and Facade patterns to simplify expansion to new languages.
Implemented quiz logic with randomized questions, point tracking, and progression gating.
