CoinTracker is a cryptocurrency tracking web app built using the MERN stack, designed to provide users with real-time market insights and a smooth user experience.

The application integrates the CoinGecko API to fetch up-to-date cryptocurrency data, while React Table is used to display interactive market charts and insights. It also features secure authentication with protected routes, enabling users to sign up, log in, and manage their profiles. Additionally, I implemented a blogging feature with full CRUD operations for posts.

Working on CoinTracker significantly improved my skills in both frontend and backend development. I used Formik and Yup to implement form validation across signup, signin, and blog post creation, ensuring secure and user-friendly data entry.

Building authentication and protected routes gave me deeper insight into managing sessions and security in MERN applications. I also gained experience handling third-party APIs efficiently and optimizing rendering for large data sets with React Table.

CoinTracker was one of the most practical MERN projects I built, combining real-world APIs, secure authentication, and interactive data visualization.

It gave me a strong foundation in designing full-stack apps with scalability in mind, managing protected routes, and delivering a polished UI with complex data integrations. The project prepared me to confidently tackle enterprise-level full-stack and fintech applications in my professional career.
