NutriSage

NutriSage is a nutrition platform helping users manage their health journey through a modern mobile experience—combining AI features, nutrition data, authentication, and subscription workflows.

The client wanted a nutrition platform that could help users manage their health journey through a modern mobile experience. The product needed more than a simple interface: AI functionality, nutrition data handling, authentication, subscription workflows, and reliable backend communication.

The challenge was creating a smooth user experience while connecting multiple systems—AI-powered features, nutrition information, authentication, subscription management, backend integration, and production release requirements.

I reviewed the product requirements, identified technical dependencies, and planned a scalable Flutter architecture that could support future growth without blocking the first production release.

• Chose Flutter as the primary client so iOS and Android could share one product surface and release cadence.
• Structured auth, nutrition data, and subscription flows as clear modules so each system could evolve independently.
• Planned AI and nutrition API communication with explicit loading, error, and retry states to keep the experience reliable.
• Aligned App Store / production release requirements early so shipping was part of the architecture, not an afterthought.

• Flutter mobile application
• Authentication workflows (including Apple and Google Sign-In)
• AI-powered product features
• Nutrition data and calculation workflows
• Subscription infrastructure
• Firebase and backend integrations
• Production release support

A layered Flutter client with presentation, state/business logic, and service/repository layers communicating with Firebase and nutrition/AI APIs for auth, data, and subscriptions.

1. Flutter App
2. Presentation Layer
3. State / Business Logic
4. Services / Repositories
5. Firebase · Nutrition APIs · AI Services
6. Backend / Cloud

• Connecting AI features to a usable nutrition workflow without fragile UX.
• Coordinating authentication, subscriptions, and backend state across the product.
• Meeting production and store-release requirements while the feature set was still expanding.

I implemented modular Flutter workflows for auth, nutrition data, AI features, and subscriptions, with clear API boundaries and release-ready error handling so the product could ship as a complete experience.

Delivered a complete AI-powered nutrition experience designed for reliability, scalability, and real users—with production release support in place.
