Dubizzle Tutorial
A project following the MVVM architecture with unit and integration testing. It shows a simple product list and its details. This project is a direct application of an MVVM architecture while using Moya for networking and reactive Swift for reactive binding

I developed a watch application on iOS to unlock remote doors.

Available at the link below:

I was responsible for revamping the existing mobile application and migrating it towards an MVVM design pattern and more reactive bindings as well developing features using Swift, Kotlin, Twilio, CallKit, Firebase, Reactive Swift, and so on.

I also developed several features on the community/admin portal of the product using Angular, HTML, SCC, JavaScript, Twilio, and Kibana, and Elasticsearch.

Available here:

In addition to my work on the app and portal, I also developed RESTful APIs following the command design pattern using.NET Core, C#, Razor, Twilio, Elastic Search, and Kibana.

Mobile Phone Records for Exploring Spatio-temporal Refugee Mobility

I participated in the Data4Refugees Challenge at Bogazici University in Istanbul. In that challenge, my teammates and I introduced our research and work on applying data wrangling, imputation, and modeling techniques on mobile records in order to uncover patterns regarding the refugees' mobilities and how they are impacted by events. We used Python, R, GCP to gather data and impute and cluster the data
