About · The person behind the systems

Business context.
Builder’s curiosity.

I like making the complicated feel clear—and turning good questions into useful software.

Duong (Young) DangBusiness Analyst · AI Engineer · CodeIT Group

I’m a Business Analyst and AI Engineer at CodeIT Group, working across business analysis, quality assurance, software testing, and automation. I enjoy translating complicated needs into clear workflows and systems people can actually use.

Recently, I built a retrieval-augmented generation (RAG) system for an internal knowledge base and developed an MQTT MCP integration that lets AI systems interact with MQTT devices. I’m also exploring agent workflows for real-estate research, flight search, invoice collection, and other practical tasks.

My current curiosity is about making AI tools work together: reusable skills, scripts, and end-to-end automations that can fit into tools such as Claude, Cursor, OpenClaw, Hermes, and OpenCode. I’m especially interested in what happens when these ideas meet industrial software, IoT, and Industry 4.0.

I work at CodeIT Group, a company focused on smart-industry software and solutions. The problems I’m drawn to are often at the boundaries: between a business process and a system, between operational data and a decision, or between an AI model and the tools it needs to act.

What I’m curious about

The overlap is the interesting part.

A mix of disciplines and tools that shape the questions I work on.
