Jsannemo-modal

Worked on the modal-labs/modal-client repository to deliver volume mount and sidecar volume management features for sandbox environments. Developed end-to-end support for both read-only and writable volumes, introducing new APIs and proto RPCs to streamline integration with sandbox lifecycles and improve restoration fidelity. Enhanced commit-on-exit semantics for sidecar volumes, enabling deterministic cleanup and more reliable recovery workflows. Leveraged Go and Python for backend development, utilizing Protocol Buffers and gRPC to define and implement robust API contracts. The work focused on improving container orchestration, reducing manual intervention, and enabling faster rollout of container-based workloads through safer and more flexible sandbox workflows.
