Doron Tsur

Platform & Distributed Systems Architect

Platform and distributed systems engineer with 15 years building the infrastructure other teams rely on: large scale search, data pipelines, event driven systems, and the IaC underneath them. Works end to end: architecture, the hard performance core, and the operations to run it. Test driven by default. Most comfortable turning an ambiguous platform problem into something other engineers can build on.
