About

I’m a passionate Mobile Application Developer with 3+ years of experience creating meaningful, scalable, and high-performance applications using Flutter and Kotlin. I thrive on building digital products that add real value—either by improving daily life, enhancing business efficiency, or simply solving meaningful problems. I believe good software doesn't just work—it empowers. Throughout my career, I’ve had the opportunity to work with startups, corporate environments, and intercontinental teams—both remotely and on-site. This range of experience has shaped my ability to collaborate in synchronous and asynchronous environments, adapt quickly, and take full ownership of the products I develop. My technical stack includes: Flutter, Kotlin, and Jetpack Compose MVVM, Clean Architecture, and Riverpod for scalable architecture RESTful APIs, Firebase, Google Play Console, Retrofit, and Git Experience in integrating payment systems, device pairing, push notifications, and real-time data synchronization I’ve independently developed production-level apps, such as: A multi-flavored Flutter app with Firebase integration, Google Sign-In, push notifications, and Iyzico payment system. An e-transformation application using Kotlin and Java, integrating SOAP and REST APIs, and optimizing builds through Gradle automation. Scalable apps across domains including e-transformation, telecommunication, smart systems, and interactive content. In addition to mobile development, I have experience with WordPress, JavaScript, SCSS, and PHP, particularly from freelance and contract-based web projects. I’m a strong communicator and fluent in English, which allows me to work efficiently with international teams. I'm also an open-source enthusiast and a graduate of industry-recognized bootcamps focused on Flutter and Kotlin development. What sets me apart is not just my ability to code, but my problem-solving mindset, my drive to continuously improve both the product and the process, and my genuine excitement for building software that creates real impact.
