PROFILE
Tamarzanzouri
Tamar Zanzouri developed robust automation and error recovery features for the Opentrons/opentrons repository, focusing on hardware workflows and user-facing reliability. Over 11 months, Tamar engineered deck configuration systems, advanced error handling for stacker and shuttle operations, and enhanced UI components to guide operators through complex recovery scenarios. Leveraging React, TypeScript, and Python, Tamar refactored state management, integrated addressable areas for fixture placement, and implemented modular overlays for protocol design. The work emphasized maintainability through unit testing and Storybook-driven UI development, resulting in resilient, scalable solutions that reduced operator downtime and improved the clarity and traceability of robotic protocol execution.
