iOS Lead Developer
& Swift Architecture Expert

I help product teams ship resilient, scalable iOS apps with Clean Architecture, modern Swift, and AI-assisted development. 13+ years building mobile systems at scale — currently Lead iOS at Sephora. I work with CTOs and mobile leads whose codebase has outgrown its architecture, and with conference teams who need a talk their senior engineers will actually argue about.

What senior engineers say about it

  • AI-driven development is something you need to understand today. If you ignore it, you fall behind. This book does a great job helping to get oriented in this space. […] The content is focused and straight to the point. Definitely a must-read.

    Artem Mirzabekian Artem Mirzabekian Lead iOS Engineer at Sovcombank · 10+ years scaling mobile platforms

  • This book is essential for any Swift developer (of any level) looking to solidify what Swift looks like in the age of AI. […] As a Lead, I'll be recommending this to my developers, for sure.
