⏱️ Time Tracker Mobile App
A simple productivity app built with React Native + Expo 🚀
I built a mobile time-tracking app that lets users create activities and track time using stopwatch-style timers ⏲️. Each activity has its own timer that can be started, stopped, updated, or deleted — all within a clean, mobile-first interface 📱.
Highlights:
Activity-based timers ➕
Start/stop stopwatch tracking ▶️ ⏹️
Update & delete timers ✏️ 🗑️
Clean, responsive UI ✨
Tech: React Native ⚛️ • Expo 🚀 • JavaScript
A lightweight project demonstrating state management, timer logic, and interactive mobile UI in React Native 💡

Hey Contra fam! 👋
I’m excited to share one of my favorite projects — an Expense Tracker App I built to help users manage their spending effortlessly.
Users can log their expenses by entering details like the name, amount, and date. The app then neatly organizes this data into two screens:
• 💸 All Expenses – showing every recorded expense and the overall total.
• 📅 Recent Expenses – showing only expenses from the past 7 days, along with a 7-day total.
I implemented smooth navigation using React Navigation, combining a Native Stack Navigator and Bottom Tabs Navigator for a clean, intuitive flow.
The data can also be stored locally or synced with a backend (like Firebase or a custom API) for persistence.
This project helped me refine my skills in state management, data persistence, and navigation architecture in React Native. 🚀

Hi Contra Fam.
Hey Contra fam! 👋
I’m excited to share another one of my mobile projects — a Meals App that lets users explore dishes from around the world! 🌍
Users can browse meals grouped by categories, tap any meal to view full details — including its photo, ingredients, and step-by-step cooking instructions — and even save their favorites to a dedicated “Favorites” screen. ❤️
A big part of this project was implementing smooth navigation using React Navigation, combining both Stack and Drawer Navigators for an intuitive user experience.

🌦️ React Native Weather App
A fast, clean weather experience built with React Native + Expo
This is one of the very first mobile apps I built a long time ago — a simple and responsive mobile weather app that lets users search any city and instantly view real-time weather conditions. The app uses the OpenWeatherMap API to fetch coordinates and live weather data, then displays temperature, conditions, humidity, wind details, and more in a clean, user-friendly interface.
What I built:
City-based search with automatic geocoding
Real-time weather data integration
Smooth, responsive UI with custom styling
Secure API handling and optimized performance
Tech: React Native • Expo • JavaScript • OpenWeatherMap API
A lightweight project that demonstrates API integration, mobile UI development, and polished React Native execution.

Hey Contra fam! 🎯
Here’s a fun number game I built — you think of a number, and the app tries to guess it!
It keeps taking turns until it gets it right, then tells you how many tries it took. Once it’s done, you can hit replay and challenge it again. 😄

Hi Contra family! 👋
This was one of my very first projects when I started building mobile apps, so I thought it’d be perfect to share as my first project here on Contra.
It’s a simple app — kind of like a to-do list — where users can register the courses they plan to study, and mark them as completed by tapping to delete them.
