I specialize in Swift, SwiftUI, and Objective-C, and I enjoy working across architecture, implementation, release, and product iteration. I have contributed to high-impact consumer applications, including the Turkish Airlines app, where I helped improve onboarding, identity verification, payment support, and release stability for a large-scale loyalty ecosystem. I focus on building reliable, maintainable features that improve user experience and reduce operational load. At Rapsodo, I grew into a senior role and helped lead an iOS scrum team while delivering multiple apps for a sports analytics platform. I have experience collaborating with product and delivery teams, reviewing code, distributing tasks, and improving performance through better architecture and debugging. Earlier in my career at Mental Segment, I built an iOS application from scratch for a screen-free learning device used by children with speech challenges. That work strengthened my ability to connect mobile apps with hardware, Bluetooth communication, local storage, and media processing. I also build independent apps as side projects, taking ideas from concept to App Store release on my own. These projects have helped me sharpen my product thinking, design sensibility, and ability to move quickly with AI-assisted development tools. I am motivated by product-driven engineering, clean architecture, and shipping useful software that creates measurable impact. I am open to opportunities where I can continue building modern iOS experiences and contribute at a senior level. ## Skills 21 capabilities[Architecture](https://jobicy.com/talent/architecture.md)[Bluetooth Low Energy](https://jobicy.com/talent/bluetooth-low-energy.md)[CI CD](https://jobicy.com/talent/ci-cd.md)[Code Review](https://jobicy.com/talent/code-review.md)[Combine](https://jobicy.com/talent/combine.md)[Debugging](https://jobicy.com/talent/debugging.md)[Embedded Systems](https://jobicy.com/talent/embedded-systems.md)[iOS Development](https://jobicy.com/talent/ios-development.md)[JSON](https://jobicy.com/talent/json.md)[Memory Management](https://jobicy.com/talent/memory-management.md)[MVC](https://jobicy.com/talent/mvc.md)[MVVM](https://jobicy.com/talent/mvvm.md)[Networking](https://jobicy.com/talent/networking.md)[Objective C](https://jobicy.com/talent/objective-c.md)[Performance Optimization](https://jobicy.com/talent/performance-optimization.md)[Product Development](https://jobicy.com/talent/product-development.md)[REST APIs](https://jobicy.com/talent/rest-apis.md)[Swift](https://jobicy.com/talent/swift.md)[SwiftUI](https://jobicy.com/talent/swiftui.md)[Team Leadership](https://jobicy.com/talent/team-leadership.md)[UIKit](https://jobicy.com/talent/uikit.md) ## Tech stack & tools Working toolkit ### Application Hosting [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/cloudflare/cloudflare-original.svg) Cloudflare](https://jobicy.com/talent?tool=cloudflare.md)[![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/firebase/firebase-original.svg) Firebase](https://jobicy.com/talent?tool=firebase.md)[![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/jenkins/jenkins-original.svg) Jenkins](https://jobicy.com/talent?tool=jenkins.md) ### Collaboration [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/jira/jira-original.svg) Jira](https://jobicy.com/talent?tool=jira.md) ### Data Stores [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/mysql/mysql-original.svg) MySQL](https://jobicy.com/talent?tool=mysql.md) ### Design [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/figma/figma-original.svg) Figma](https://jobicy.com/talent?tool=figma.md) ### Development [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/git/git-original.svg) Git](https://jobicy.com/talent?tool=git.md)[![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/github/github-original.svg) GitHub](https://jobicy.com/talent?tool=github.md)[![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/wordpress/wordpress-original.svg) WordPress](https://jobicy.com/talent?tool=wordpress.md) ### Languages & Frameworks [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/html5/html5-original.svg) HTML5](https://jobicy.com/talent?tool=html5.md)[![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/swift/swift-original.svg) Swift](https://jobicy.com/talent?tool=swift.md) ### Mobile [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/xcode/xcode-original.svg) Xcode](https://jobicy.com/talent?tool=xcode.md) ## Experience Career history ### iOS Developer · Turkish Airlines Technology May 2023 – PresentI rewrote the app’s sign-in and sign-up flow and built Digital Profile to streamline onboarding into the Miles&Smiles loyalty program.
