What I'm looking for

I seek senior/principal mobile engineering roles where I can modernize products, lead teams, integrate AI features, and improve security and CI/CD in an agile, collaborative environment.

I am a seasoned iOS software engineer with over 20 years of experience in mobile and systems development, an MSc in Electrical Engineering and Computer Science, and a track record of modernizing legacy apps, implementing secure systems, and delivering CI/CD automation. I have led cross-functional teams, mentored engineers, and driven architecture and security improvements across greenfield and legacy projects.

My hands-on expertise includes Swift, Objective-C, SwiftUI, Combine, concurrency, and integrating AI/LLM features for improved UX; I have successfully built banking and utility apps from scratch, introduced TDD and reactive practices, and implemented scalable monetization and release pipelines to increase velocity and reliability.
