I am a Full-Stack Developer with hands-on experience building modern applications from end to end. I have worked on projects that involve designing intuitive user interfaces, developing scalable back-end systems, and integrating external APIs. My experience includes developing Android applications using Kotlin and Jetpack Compose, implementing modern architectural patterns such as MVVM, and working with asynchronous programming using Coroutines and Flow. I have also built systems that consume real-time data, handle API communication with Retrofit, and manage local persistence using Room and DataStore. On the back-end side, I have experience working with cloud-based services such as Firebase, including authentication, real-time databases, and push notifications. I am comfortable designing data flows, structuring clean architectures, and ensuring efficient communication between client and server. I focus on writing clean, maintainable code and continuously improving my skills by building real-world projects. My goal is to deliver reliable and well-structured solutions while following best development practices.
