# Matt Docherty

> Applied AI Engineer at Credit Karma (7 years) building production AI and automation systems — RAG, agents, and enterprise automation — that remove operational overhead at scale.

If something’s being done manually and it doesn’t need to be, that’s the problem I’m there to solve. Usually before anyone realises it was a problem.

## Selected impact

- Cut IT ticket volume 46% YoY with a RAG-powered support bot (Vertex AI Vector Search + Gemini on GCP) that handled 45,000 tickets and reclaimed 3+ FTEs of capacity.
- Automated temporary system access end to end on Workato: 6,238 requests, median resolution 3.7 hours → 3 minutes (74× faster), recovering $240k in annual overhead.
- Generated $500k+ in annual cost savings and eliminated 2,500+ hours of manual work per year through enterprise automation strategy at Credit Karma.
- Built a BigQuery-backed analytics dashboard and weekly AI-written email digest, adopted from VP up to the SVP of Engineering.

## Built independently

- Personal AI Memory System: A RAG system that gives Claude persistent context across conversations. An Obsidian knowledge base on Google Cloud Storage, served through a remote MCP server on Cloud Run, with scheduled maintenance agents running on a headless Mac Mini and n8n. Versioned, authenticated, and in daily use.
- Workout & Body-Composition MCP: A self-hosted training platform. It's an MCP server on Cloud Run backed by Cloud SQL (Postgres), with a React and Tailwind progressive web app served from the same service. Token-based auth, stateless, and it scales to zero. It logs every session and InBody scan, then surfaces analytics, goals, and recovery patterns.
