What I'm looking for

I’m looking for an iOS role where I can ship high-impact Swift apps, optimize performance and UX, and lead engineering decisions—collaborating closely with product teams while building reliable integrations and clean, scalable architectures.

I’m a Senior iOS Engineer with 5+ years of hands-on experience designing, developing, and shipping high-quality, scalable iOS applications across e-commerce, AI-powered tools, IoT/smart home, EdTech, and marketplace platforms. My core strength is building clean, maintainable codebases with Swift, UIKit, async/await, Combine, and protocol-oriented design patterns, while delivering exceptional user experiences.

I’ve led iOS development pods, mentored engineers, and driven technical decisions that align with product and business goals—most notably through ZenImmersive, where I architected modular networking, built a complete StoreKit 2 subscription/IAP system, and integrated Philips Hue v2 real-time lighting control. I’m also passionate about performance optimization and staying current with Apple’s evolving platform ecosystem, from secure authentication flows (Sign in with Apple/Google) to complex third-party SDK and API integrations.
