What I'm looking for

I seek a role where I can build user-centered iOS products, mentor teams, work cross-functionally, and grow toward ML/computer-vision leadership.

I am a results-oriented iOS software engineer with over 20 years of software development experience across telecommunications, core banking, and maritime terminal systems. I have led and contributed to more than 35 projects since 2008, including long-term work as a subcontractor maintaining major Verizon software and building top-30 App Store products.

My iOS expertise spans Swift, SwiftUI, UIKit, Combine, MVVM, CLEAN architecture, SOLID principles, Core Data, HealthKit, Twilio and Zoom integrations, and HIPAA/SOC2/PCI-aware implementations. I have delivered high-impact features—secure messaging, health-data sync, scheduling with Zoom SDK, onboarding journeys, analytics/monitoring with Datadog, and performance optimization—while maintaining strong testing and code-quality practices.

I am seeking to apply my deep engineering skills, cross-functional collaboration, and product-minded approach to help teams build reliable, user-centered mobile experiences. I plan to pursue a Master's in Computer Science focusing on machine learning and computer vision to broaden my technical leadership and impact.
