PROFILE
Daniel Norberg
Over six months, contributed to modal-labs/modal-client by building and enhancing backend systems for container orchestration, task state management, and secure storage. Developed gRPC-based APIs and Protocol Buffers to enable scalable container lifecycle operations, directory mounting, and full filesystem snapshots, improving automation and reproducibility. Integrated customer-supplied encryption key (CSEK) support for directory snapshots, strengthening data security and compliance. Improved performance and observability in blob uploads through optimization and instrumentation. Delivered CLI enhancements for dynamic feature toggling and maintained robust unit testing practices. Work was primarily implemented in Go and Python, with a focus on backend development, encryption, and cloud storage integration.
