At PhiDimensions, I built an AI-assisted engineering system for a large multi-repository codebase, combining an architecture DAG with automated validation, specialized agents, workflows, and MCP integrations. I also created custom document extractors with Google Cloud Document AI and fine-tuned models to improve extraction accuracy.

I’ve built full-stack products across data pipelines, APIs, and frontend experiences, including a federated search surface at PhiDimensions and API query improvements at Fluid Attacks that reduced a critical query from 15 minutes to under one second in the worst cases. My work spans TypeScript, React, Python, GraphQL, and AWS.
