I’m a Junior Developer with a passion for mobile app development and a growing understanding of full-stack development. My main focus is building smooth, user-friendly mobile applications using React Native, while also exploring the backend side of development to create complete, data-driven solutions. I have a solid foundation in JavaScript, HTML, and CSS, along with hands-on experience connecting apps to databases and working with Postbird (PostgreSQL) to manage and interact with backend data. This combination helps me understand the full flow of an application—from front-end interface to backend logic and data management. I’m eager to collaborate on real projects, learn from experienced developers, and contribute to meaningful work. Whether it’s testing, creating new features, integrating APIs, optimizing database queries, or refining UI design, I’m always ready to grow and add value to a team. Key Skills: React Native (mobile app development) JavaScript (ES6+) HTML5 & CSS3 Backend integration & REST APIs Database management (Postbird / PostgreSQL) UI/UX fundamentals Version control (Git) Debugging & problem-solving Currently looking for: Junior developer roles, freelance projects, or internships where I can apply both my front-end and backend knowledge to help build engaging, data-driven applications.
