Selected projects

• Prismor — Open-source contribution

  PrismorSec builds a security and governance layer for AI coding agents and production agent frameworks, evaluating tool calls before execution and recording tamper-evident audit evidence. My merged contribution improved its AI proxy so clients can distinguish upstream provider authentication failures from Prismor policy refusals, across buffered and streaming responses, and added guidance for local OpenAI-compatible backends.
