AI Engineer at German Research Centre for AI (DFKI) / Gretchen AI

• Designed and shipped multimodal AI agents that cross-reference images with reverse-image-search results and web articles to produce citation-backed verdicts on authenticity.

• Implemented an automated evaluation pipeline using Promptfoo, combining automated scoring, schema validation, and metrics to regression-test prompt and model changes before rollout.

• Orchestrated asynchronous, high-throughput AI inference pipelines using Prefect and FastAPI, running tasks in parallel to keep latency low under concurrent load.

• Designed the Supabase (Postgres) schema and Alembic migrations backing the agents, and configured Supabase Auth with custom role-based permissions.
