iOS Developer · 5+ Years Experience

Clean code,
sharp solutions

I design and engineer native Apple applications built to last — thoughtful architecture, maintainable Swift codebases, and interfaces that feel fluid and natural.

About
Hakob Ghlijyan portrait

Engineer by trade, architect by instinct

I am an iOS developer with 5+ years of experience specializing in the modern Apple technology stack. My expertise covers both bleeding-edge approaches (SwiftUI, Combine, SwiftData, Structured Concurrency) and classic production-tested fundamentals (UIKit, Core Data, AutoLayout, SnapKit).

Experience across the entire mobile application lifecycle: from architecture design (MVP, MVVM, VIPER, Clean Architecture) and modular UI kit libraries to App Store publication, CI/CD pipelines, and deep memory/performance profiling with Instruments.
