What I'm looking for

I seek a senior mobile role where I can lead architecture and SDK/ad‑tech integrations, mentor engineers, and build scalable, privacy‑compliant products in a fast‑paced, impact-driven team.

I am a Senior iOS Developer with 7+ years of experience building scalable mobile applications and ad systems. I currently develop in-house advertising and analytics systems for a global mobile games leader.

At EasyBrain I helped build ad solutions used across products reaching over 750 million users, integrated major ad networks in production apps, and developed modular libraries for ad management, consent, tracking, and SDK integration.

I work primarily in Swift and Objective-C, applying Clean Architecture, Protocol-Oriented Programming, and modular design while using tools such as Combine, StoreKit, AppTrackingTransparency, SKAdNetwork, Firebase, Charles Proxy, Git, and Jira. I regularly investigate low-level SDK issues, collaborate with analytics and backend teams, and provide documentation and technical support to enable cross-team adoption.

I mentor junior engineers and lead architecture discussions, and I am passionate about growing into leadership and architectural roles where I can drive high-performance, privacy-compliant solutions that deliver measurable business impact.
