I spent four years at Ordulu Teknoloji building and maintaining a secure end-to-end encrypted Swift chat app used by 200K+ active users. I worked across real-time messaging, REST and WebSocket layers, offline persistence, VoIP calling, and error and retry paths.

I improved the app’s GRDB/SQLite schema and migrations, built programmatic UIKit interfaces, and moved heavy work off the main thread with Swift Concurrency, GCD, and Operations. I also used Xcode Instruments to resolve hangs, hitches, and memory leaks, improving scrolling performance.

I co-founded Lib Co. as its sole engineer, building a multi-tenant SaaS platform that harvests COUNTER 5 and 5.1 SUSHI usage data from 320+ vendor platforms and deploying a live pilot. I’m now looking to return to iOS development full time, bringing experience with Swift, UIKit, SwiftUI, Kotlin Multiplatform, and end-to-end product delivery.
