What I'm looking for

I am seeking a role building native iOS apps where I can own features, improve performance, and work in an Agile team that values code quality and growth.

I am an iOS developer focused on building scalable, high-performance native mobile applications using Swift and SwiftUI. I specialize in architecting clean UI/UX with MVVM and MVC patterns and have hands-on experience with Core Data and Realm for persistent storage.

At Brandsmashers Tech I contributed to production releases by resolving over 15 critical UI/UX and core functionality issues and reduced time-to-deployment by 30% by diagnosing and fixing a critical build problem. I work effectively in Agile teams and use Git, BitBucket, JIRA, and Slack for collaboration and delivery.

My projects include migrating a web-based marketing automation platform to a 100% native iOS app, implementing automated social posting and background processing, and building a realtime Hacker News feed app with sub-200ms fetch latency through optimized asynchronous networking.

I continually strengthen my foundations in data structures and algorithms (300+ problems solved) and hold iOS and related certifications. I bring a pragmatic, results-oriented approach and enjoy solving complex integration and performance challenges on mobile platforms.
