Caloriv – Nutrition Tracking

Problem

Accurately tracking daily nutrition is harder than it looks. Most tools are either too complex or too shallow. The goal was to build a streamlined, modern web app that handles the math and lets users focus on their health.

Tech Stack

• Frontend: Next.js + React for a fast, SEO-friendly, interactive UI
• Styling: Tailwind CSS for a clean, responsive design
• Language: TypeScript for type safety and maintainability
• Storage: SQLite for lightweight, persistent data storage
• Deployment: Azure Linux VM

Key Features

1. BMR/TDEE Calculation: Implements the Mifflin-St Jeor equation to estimate daily caloric needs based on age, weight, height, and activity level.
2. Calorie Logging: Users can log meals and track intake against their daily target.
3. Persistent Storage: All user data is stored in SQLite, ensuring logs persist across sessions.

Architecture Decisions

• Chose SQLite over a hosted database to keep infrastructure simple and cost-free for a solo project.
• Used Next.js App Router for co-located server and client logic, reducing API boilerplate.

Next Steps

• Integrate a food database API (Edamam or Nutritionix) for real-time macronutrient search.
• Add user authentication and historical progress charts.
