IngrediScan: Android Nutrition Tracker App

IngrediScan is a collaborative mobile application designed to help users make healthier food choices by instantly displaying detailed nutritional information from scanned barcodes. Built using Kotlin and Jetpack Compose, the app retrieves real-time data including calories, macronutrients, and additives from the USDA FoodData Central API and presents it in a clean, user-friendly interface. Rather than decoding complex ingredient labels or manually entering meals, users can quickly assess their food choices in seconds.

The project was developed by me and a team of 9 other students. Working together in a structured environment, we applied real-world software engineering practices to bring the application to life. I contributed to both front-end development and back-end integration, ensuring the app was responsive, intuitive, and functionally robust.

Through this experience, I gained hands-on skills in team collaboration, version control with Git and GitHub, and issue tracking using pull requests and branch-based workflows. We communicated regularly through stand-ups, coordinated features across roles, and practiced resolving merge conflicts and debugging shared code in a multi-developer environment.

Firebase was used to handle user authentication and secure data storage, while Jetpack Compose streamlined UI development for a modern Android experience. The result is a fast, reliable, and FDA-aligned nutrition tracking app that’s built with real users in mind.
