Professional Overview

I'm a Senior AI Engineer who ships production LLM systems, not demos. I help companies turn document-heavy workflows into pipelines that survive real traffic: multi-agent checks, structured extraction with schema validation, evaluation, and cost control per document. Python, FastAPI, cloud workflows, serverless.
