What I'm looking for

I seek a product-driven, collaborative team role where I influence architecture, ship high-quality mobile features, and work on cross-platform solutions and analytics.

I am an iOS developer with over five years of experience building complex mobile applications focused on rich UI/UX, performance and reliable integrations. I specialize in Swift, iOS tooling and optimizing app startup, memory and multimedia processing.

I have delivered production apps across domains including social networks, smart-home/residential management, education and wellness, and I publish to the App Store and support analytics, push notifications and CI/CD pipelines. I collaborate closely with backend engineers, designers and QA, participate in sprint planning and code reviews, and drive architectural decisions.

My accomplishments include measurable improvements — faster cold start, reduced memory and call failures, and faster bug analysis — and I am interested in product-driven teams where I can contribute to architecture, cross-platform solutions (KMM/Flutter) and robust analytics.
