Senior Software Engineer
Build the platform and open-source runtime for deploying, observing and governing AI agents across CrewAI OSS, Enterprise and the Agent Control Plane.
- Designed and delivered an end-to-end AI policy system, from runtime enforcement in CrewAI OSS to policy authoring and deployment in the Agent Control Plane, backed by a proof of concept covering 21 policy cases.
- Rebuilt the Agent Control Plane metrics foundation on Cube, resolving slow dashboards and database out-of-memory failures.
- Established observability for critical platform services with Prometheus and Grafana, surfacing issues such as a 70% drop-off in an integration connection funnel and trace ingestion rejecting every sample.
- Delivered enterprise JIT SSO and team mapping for Entra ID, Okta, Auth0 and Keycloak, with setup guides for customer onboarding.
- Improved execution tracing across OSS and Enterprise, including human-in-the-loop support and fixes for incomplete or stuck traces.

Senior Software Engineer
- Built Price Sheet Matching, which catches pricing errors on invoices so customers can issue credits or recover overcharges, recovering hundreds of thousands of dollars within a few iterations. Since products were not pre-registered, identified them using embeddings, vector similarity search, classification and AI agents.
- Built an API gateway that distributes invoice-processing requests across multiple data-extraction systems.
- Worked on OCR-based invoice detection and reading, and optimized the back-office workflow for processing invoices.
- Improved developer experience by introducing APM and error tracking and modernizing the codebase and testing tools.
