ABOUT ME

Senior Android developer

I have 8 years of experience in software development, especially in native Android development. I’ve worked on so many projects, both individually and professionally. Actually, I graduated from Dokuz Eylül University in my country and I graduated as a top student who has the highest GPA (grade point average). After that, I started to work for one of the biggest white-good and technology companies in Turkey, which is called Vestel. I’ve worked there for five years and I worked in two different departments in that company. I became familiar with AOSP project and the development of IoT applications for our users. I've used Git, Jira, Gerrit tools with Java and Kotlin programming languages.

In the next two years, I had the chance to work for two more companies and I've used Jetpack Compose UI toolkit alongside with Jetpack navigation for these projects.

I personally try to use the latest technologies and best practices. I really care about software quality and care about SOLID principle in software development.
