Derek Fox

Senior GenAI Engineer — I build production LLM systems that survive contact with the enterprise.

4 years shipping agentic architectures, multi-hop RAG pipelines, and evaluation frameworks at scale. Currently at Deloitte (finance AI), previously RevGen Partners. Actively building in public.


What I Ship

Project What it does
ReasonForge Modular math toolkit for LLMs — 111 tools, 7 MCP servers, exact computation via SymPy/NumPy. Listed on awesome-mcp-servers.
UpTier MCP-powered task manager that lets Claude AI prioritize your work. Desktop app with Eisenhower matrix, quick-win scoring, and goal tracking.
DeckSnag CLIP-powered slide capture — auto-detects slide transitions in video and exports to PowerPoint, PDF, or images.
TransitGuard Predictive safety intelligence for Chicago CTA. XGBoost + DBSCAN on 50K+ crime incidents with RAG chatbot interface. Northwestern MSDS capstone.

Production Work

  • LLM-as-a-Judge evaluation framework - reduced functional testing time by 90% across production AI outputs
  • Finance agents on Google Gemini Agentspace - agentic workflows with human-in-the-loop oversight for high-stakes enterprise contexts
  • Multi-hop RAG architecture - multi-modal document processing on GCP (Vertex AI, Document AI), optimized for latency and cost at scale
  • ML lead routing engine - ranking, ensemble, classification, and forecasting models deployed across enterprise client engagements
