PROFILE

Jonas Neubert

Worked on backend improvements and API security across two repositories, focusing on type safety and deployment configurability. In agno-agi/agno, addressed a type-safety issue by updating the Agent class’s tool handling annotation from List to Sequence, leveraging Python’s type hinting to reduce runtime errors and align with covariant typing best practices. For BerriAI/litellm, developed a feature to control OpenAPI endpoint exposure by introducing a NO_OPENAPI environment variable, allowing deployers to disable the /openapi.json endpoint for enhanced security and compliance. Demonstrated skills in Python, backend development, and testing, with an emphasis on maintainability and secure, configurable deployments.
