Team Leadership

Health Hero: Mobile Nutrition Planning

A Flutter meal-planning app that generated weekly plans, analysed eating habits, and produced nutrition reports.

Highlights

  • Led a six-person team across frontend, backend, and design.
  • Defined the mobile structure, app state, and REST API integration.
  • Added offline meal recognition with a pre-trained TensorFlow Lite model.

Context

Health Hero was designed to help young people plan meals, understand eating habits, and get simple nutrition feedback on mobile.

Role and scope

Vincent led a team of six, coordinating frontend, backend, and UI/UX work while also contributing as a full-stack developer.

He defined the Flutter project structure, the major screens, and global app state with Provider, then wired up the connection between the mobile app and the backend REST APIs.

Technical decisions

Flutter handled the mobile app, and Express with MongoDB powered the backend. TensorFlow Lite handled the offline meal-segment recognition.

The backend routes were tested with Mocha and Chai, with a CI/CD pipeline handling server delivery.

Leadership scope

The work spanned team coordination, mobile architecture, and hands-on machine-learning exploration.
