Calorie Tracker
Track meals via photo; AI extracts nutrition.

- SQLite + Docker Compose
- JWT auth, metrics

- AI-personalized calls with child details
- Stripe payments + webhook handling
- Supabase database + Docker ready

Your Time Ahead
A reflective life expectancy calculator based on lifestyle choices.
A contemplative web application that helps users explore their remaining lifetime based on personal habits and lifestyle factors.
Not a medical prediction — but a structured, data-informed invitation to reflect on time, health, and priorities.
The application guides users through key inputs, calculates an estimated life expectancy, and allows them to track changes over time, encouraging conscious decision-making rather than false certainty.
- Lifestyle-based life expectancy calculation
- User accounts with saved history and progress tracking
- Clean, responsive UI with dark mode support
- Modern React frontend with fast, lightweight performance
- Secure backend API with PostgreSQL storage
- Docker-ready architecture for easy deployment

Fearless
A reflective courage-tracking app for people who choose to act despite fear.
A modern web application that helps users build intentional courage through simple weekly self-reflections.
Instead of suppressing fear, Fearless encourages you to notice anxiety, act despite it, and track meaningful moments with the people who matter most.
Not therapy. Not diagnosis.
But a structured way to build emotional awareness, confidence, and accountability over time.
The application guides users through weekly reflections, allows them to record fear-facing actions, anxiety levels, goals, and family moments, and then visualizes progress over time — making courage a measurable personal practice rather than a vague ideal.
- Weekly self-reflection tracking
- Progress & trend analytics
- Personal goal setting
- Multi-language
- Secure private accounts
