About

Professional summary

I am a Senior iOS Engineer with more than eight years of experience building, scaling, and maintaining production iOS applications and SDKs. I specialize in Swift, SwiftUI, UIKit, modular architecture, and high-quality mobile engineering practices.

I have worked across fintech, transportation, logistics, insurance, construction technology, and travel products. My experience includes delivering applications used by millions of users as well as SDKs integrated by external partners.

I design maintainable mobile solutions using patterns such as MVVM, VIPER, RIBs, dependency injection, SOLID, and domain-driven design. I am comfortable modernizing legacy codebases, improving modularity, and optimizing critical user flows.

I have strong experience with Swift Concurrency, REST APIs, OAuth 2.0, testing, CI/CD, and application performance analysis. I use tools such as Instruments, MetricKit, Fastlane, GitHub Actions, and XCTest to improve reliability and delivery speed.

I have also worked on ARKit and LiDAR-based 3D capture workflows, including optimizations for real-time processing and computer vision data pipelines. I enjoy solving complex technical challenges with practical, scalable solutions.

I collaborate effectively with distributed product, backend, QA, machine learning, and engineering teams across time zones. I contribute through technical design, code reviews, mentoring, and clear communication with both stakeholders and developers.
