About

React Native developer with about a year of hands-on experience building mobile apps for Android and iOS. I've worked on real projects from scratch handling user authentication, REST API integration, Firebase, state management with Redux and Context API, and local data storage with AsyncStorage. I pay attention to UI details and try to make apps feel smooth and responsive on different screen sizes. I also have some backend exposure I've worked with Node.js, Express.js, and databases like PostgreSQL and MongoDB, mostly while building and consuming APIs for my apps, which helps me work more independently. What I work with: React Native · JavaScript (ES6+) · Firebase · Redux · REST APIs · Expo · Git Getting familiar with: Node.js · Express.js · PostgreSQL · MongoDB Currently looking for React Native roles or freelance work where I can keep growing and contribute to a real product.
