What I'm looking for

I seek senior engineering roles owning end‑to‑end architecture in cloud‑native teams, focused on performance, scalable systems, and mentoring engineering teams.

I am a full‑stack and mobile engineer with 7+ years building high‑performance apps across iOS, Android, and web, delivering real‑time streaming, AI‑assisted features, and cloud‑native backends at scale.

I own architecture end‑to‑end — from SwiftUI and Jetpack Compose on device to React, Angular, Next.js on web and FastAPI/Node on the server — and am known for squeezing latency and costs while hardening release pipelines and leading distributed teams to production outcomes.

My recent achievements include building serverless backends on AWS Lambda handling 50K+ daily API calls, introducing GraphQL federation, cutting TTFB by 40% with edge rendering, shipping offline‑first sync with Realm and CloudKit, and integrating on‑device CoreML for privacy‑preserving inference.
