What I'm looking for

I seek impactful roles building high-performance iOS apps or SDKs, in teams valuing reliability, observability, and scalable engineering practices.

I am a Senior iOS Engineer with 8+ years building high-performance Swift applications and platform SDKs that serve millions of users. I architected a Feature Flag SDK used by 30M+ users at PicPay and led a photo editing suite reaching 100M+ downloads at Air Apps, with deep expertise in SwiftUI, UIKit, Metal, and Swift Concurrency.

I co-founded and engineered a cashless payments platform, improved CI/CD and release automation at OLX, and pioneered first-to-market SharePlay features and large-scale migrations from UIKit to SwiftUI. I bring a pragmatic, test-driven approach to shipping reliable products under load, and I value observability, performance, and developer ergonomics.
