Future Cats — Enterprise RAG

FUTURE CATS · CONSULTING · 2025—NOW

Natural-language search across compliance docs and label regulations for an enterprise client in the food industry. Hybrid retrieval + re-ranking, OpenAI & Claude orchestration, OCR ingestion, per-tenant permissions, streaming responses. Label-compliance agents cut manual review from hours to minutes.

Agentic dev toolkit

PERSONAL FRAMEWORK · 2025—NOW

My operating system on Claude Code: custom skills, subagents, MCP servers, persistent memory. Spec-driven SDLC — plan as spec, delegate to agents, review human-in-the-loop. One engineer, team-scale output.

ABOUT / METHOD

I work AI-first: every feature starts as a written spec, implementation is delegated to agentic coding systems, and nothing ships without human review. That's how one engineer delivers like a team — without the slop.
