What I'm looking for

I seek a senior iOS or technical lead role where I can build scalable mobile products, mentor teams, drive CI/CD and backend integrations, and contribute to a collaborative, Agile environment focused on measurable user impact.

I am an accomplished iOS engineer and team lead with over 12 years of experience in mobile app development, full-stack engineering, backend infrastructure, and IT leadership. I specialize in Swift, SwiftUI, Objective-C, Xcode, and have published multiple apps to the App Store while optimizing systems with AWS and Serverless frameworks.

I have led cross-functional teams, implemented CI/CD pipelines (Fastlane, Bitrise), integrated Firebase services, and improved deployment and uptime metrics through automation and rigorous QA. My backend experience includes Laravel Lumen, RESTful APIs, and scalable architectures handling high daily request volumes.

I hold a BS in Computer Engineering (Cum Laude) and combine technical depth with practical IT administration, network management, and Agile delivery to produce high-impact user experiences and reliable operational systems.
