Hi, I'm Sanghwa Na 👋

Linkedin

I architect Gen AI solutions with customers and maintain working implementations that developers can deploy immediately. Most of my work is hands-on: designing real architectures, proven patterns, and battle-tested setups for AI Agents, Multi-agent systems, RAG pipelines, and scalable ML deployments on AWS.

I run the open-source Amazon Bedrock Client for Mac, a native macOS application where developers get streamlined access to AI models directly from their desktop. I also maintain several AWS sample repositories with complete agent templates and production demos.

What I work on

  • 🤖 AI Applications & Agents: Multi-agent orchestration, browser automation with Nova Act, agentic workflows, tool-calling patterns, MCP server implementations
  • 📦 Production Systems: Document processing, fraud detection, order automation, timecard processing, intelligent routing - complete with working demos
  • 💻 Developer Tools: Native macOS client for Bedrock, CLI tools, development workflows for AI applications
  • 🗂️ RAG Architectures: Simple retrieval → agentic RAG → hybrid search → multi-tenant security patterns
  • 🎓 Workshops & Content: AgentCore Deep Dive, Strands Agents, MCP Productivity Tools
