What I'm looking for

I'm seeking a role with full technical ownership scope.

At Bank Hapoalim (Bit), I designed and built an agentic AI workflow that runs the development cycle from product requirements through implementation, review, and source control. It cut average feature delivery time by 4–7× and became part of the team's everyday engineering practice.

At AU10TIX, I diagnosed and fixed hard-to-reproduce concurrency and threading defects in the iOS app, improving release stability. I also moved into backend development, joining a team of six to build and maintain the Node.js services behind the identity-verification product.

At JustEatTakeaway, I led the app's transition from Objective-C to Swift while re-architecting the codebase and continuing product roadmap delivery. The app reached a 99.5% crash-free rate, and I led a team of seven mobile engineers.

At Maccabi HealthCare Services, I was tech lead for a team of eight to nine engineers working on a member-facing health app. I identified and resolved performance bottlenecks that improved responsiveness. I'm seeking a role with full technical ownership.
