During November 2024, Mizobava developed the Parallel Browser Sessions feature for the UKGovernmentBEIS/inspect_ai repository. By refactoring the environment service in Python, Mizobava enabled support for multiple concurrent browser sessions, allowing clients to create and join distinct browser contexts independently. This backend development effort focused on concurrency management and browser context isolation, providing a scalable architecture for web automation tasks. The work leveraged gRPC for service communication and introduced a multi-session design that improves throughput, isolation, and reliability. Although no bugs were fixed during this period, the depth of the feature reflects strong skills in tooling and concurrent system design.
