Staff Software Engineer at Temporal Technologies
San Francisco, California, United States
Summary
🤩
RockstarMoshe Zadka is a Principal Engineer based in San Francisco with 24 years of experience designing and operating high‑reliability infrastructure, developer productivity platforms, and networked systems from Ethernet stacks to application protocols. He combines deep Python and Twisted expertise—contributing SMTP/POP3 virtual domain support to the flagship Twisted project—with hands‑on SRE work that has measurably reduced alert volumes and incident response times. At companies from Facebook and VMware to Anthropic and JPMorgan Chase he’s built CI/CD, monitoring, and secure deployment pipelines, and led processes for design reviews and post‑mortems that improved delivery and reliability. He has a track record of automating tedious workflows (cutting CI and service setup times from hours to minutes) and designing tooling to safely share developer data for managerial insight. Moshe is equally comfortable mentoring engineers and negotiating cross‑team or vendor integrations to solve thorny operational problems. A persistent tinkerer, he pairs low‑level networking knowledge with platform thinking to deliver practical, auditable solutions.
