About

Backend engineer with strong experience in distributed systems, real-time infrastructure, and AI-powered services — and a solid track record in iOS development.

I specialize in building systems that handle scale and complexity — high-throughput messaging pipelines, real-time agent infrastructure, and custom agentic frameworks. On the mobile side, I build native iOS apps with Swift and SwiftUI, with a focus on performance and clean architecture.

Open to backend, iOS, and AI infrastructure roles.
