Hamid Reyes

I architect and ship AI products, intelligent systems, and software solutions that connect AI, automation, APIs, data, and business systems.

What I Do

  • Work directly with LLMs, RAG, agentic pipelines, tool calling, and workflow orchestration to build systems that hold up in production, not demos
  • Turn ambiguous ideas and business requirements into system architectures, working software, integrations, and automation
  • Build and integrate backend systems through APIs, webhooks, databases, third-party platforms, and business applications
  • Design practical solutions across AI, software, automation, data, and business systems, picking whichever combination actually fits the problem

Currently

  • 🔭 Building: Enterprise Operations Intelligence for Multi-Location Restaurants an enterprise AI system built around KFC's multi-location operations, centralizing customer feedback and operational insights across a network of up to 4,300 U.S. locations

  • 🔭 Building: IntraCore AI an open-source, local-first AI workspace giving users full control over their models, memory, and data early architectural development, built in public, with FastAPI, Next.js, Ollama, LangChain, and LangGraph

  • 🔬 Exploring: Agentic AI, AI product architecture, retrieval-augmented systems, intelligent automation, AI-assisted decision systems, and multi-system AI integrations

  • 💼 Open to: full-time roles building AI products, agentic systems, or AI-driven automation platforms

An automated financial reconciliation system for a global SaaS business, integrating multiple payment gateways with accounting workflows to normalize, validate, and reconcile subscription revenue.
