DevOps & Platform Engineer · CI/CD · AWS / GCP · Kubernetes
Summary

DevOps and platform engineer with 11+ years in tech, including 8 years at Sonos where I owned CI/CD for the entire engineering organization — cutting build-failure rates from 30% to 0.9% and build times by 77%. Since 2023 I have designed, deployed, and operated cloud-native production systems independently across AWS and Google Cloud: Docker and Kubernetes, GitHub Actions pipelines, Cloudflare, and end-to-end observability. Based in Jerusalem and authorized to work in Israel.

Experience
Independent DevOps & Software Engineer — Contract
2023 — Present
  • Design, deploy, and operate cloud-native applications on AWS and Google Cloud — containerized with Docker, orchestrated on Kubernetes, fronted by Cloudflare
  • Build CI/CD pipelines in GitHub Actions using workload identity federation (no long-lived cloud credentials), automating test, build, and zero-downtime deploys
  • Own production reliability end to end: observability with Sentry and PostHog, alerting, and incident response across live services
  • Selected production builds: InsightTrader (trading-analytics SaaS, Stripe billing), Habify (habit tracker published on Google Play), SecureChat (E2E-encrypted messaging)
Build & Automation Engineer — Sonos
2019 — 2023
  • Owned CI/CD infrastructure serving the engineering org across frontend and backend systems
  • Reduced build failure rates from 30% to 0.9%, dramatically improving developer productivity
  • Cut build times by 77%, directly accelerating release velocity across all teams
  • Built end-to-end test automation frameworks using Playwright across microservices architectures
  • Validated API contracts with Postman and leveraged AWS for scalable build and deployment infrastructure
  • Mentored engineers across multiple teams on build systems, testing strategy, and DevOps best practices
Technical Support Engineer & Team Lead — Sonos
2015 — 2019
  • Led technical support teams of 3–10 engineers, managing escalations and team performance
  • Built escalation workflows and diagnostic tools for complex network interference issues
  • Bridged customer-facing support and engineering, translating field data into product improvements
