About

I have been developing iOS applications since 2012, gaining extensive expertise in the iOS development lifecycle, including creating certificates and provisioning profiles, managing necessary libraries, architecture, and deploying apps to beta and the App Store. My career highlights include developing a multi-chain iOS Wallet App at Blockchain since March 2022, where I used SwiftUI for the main UI architecture, heavily utilized async-await concurrency, and employed Combine for reactive programming. Previously, I worked at ComeOn Group, where I developed and maintained iOS platforms for their brands, using UIKit and SwiftUI with MVVM architecture and protocol-oriented programming. My journey as a Senior iOS Developer includes significant roles at ING Turkey, Bilyoner, and Tikle. At ING Turkey, I was part of a Scrum team, responsible for developing and maintaining core and UI elements of the app using Swift 5 and MVVM architecture. At Bilyoner, I contributed to developing apps for the largest betting company in Turkey, utilizing RxSwift and RxCocoa. My early experience at Tikle involved managing the entire development, testing, and release process for the GollerCepte app. Additionally, I have experience with Objective C, having developed multi-threaded apps with heavy CoreData operations at Metus and contributed to airport shuttle reservation apps at Youth. My educational background includes a degree in Electronics and Communication Engineering from Yildiz Technical University.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
