What I'm looking for

I seek a senior mobile engineering role where I can lead iOS development, mentor engineers, drive architectural decisions, use CI/CD and AI tools, and deliver high-quality, scalable apps in a collaborative, product-focused team.

I am a lead software engineer specializing in native iOS development with over eight years of experience delivering mobile applications for international clients. I have a track record of taking complex projects from concept to App Store release while ensuring compliance, reliability and maintainability.

In recent roles I led core modules for connected worker and healthcare platforms, modernized legacy Objective-C codebases to Swift, and delivered reusable SDKs and frameworks to standardize development. I emphasize unit and end-to-end testing, clean code practices, and the use of AI-driven tools and CI/CD to increase efficiency.

I mentor junior engineers, perform task planning and effort estimation, and collaborate across platforms to ensure consistent user experiences. I seek opportunities where I can continue to lead mobile engineering efforts and drive high-quality, scalable app delivery.
