ABOUT

About

Nguyễn Hải Minh is an AI engineer focused on workflow automation and products built with AI.

I have worked in AI automation since 2021. I started with sales and marketing automation and managing multi-account social media for brands. Since then I have built automation workflows, chatbots connected to LLMs and API integrations, and I help teams reduce what they spend on running AI.

Video transcript

Hey, I'm Minh. I work with AI. I build stuff that does the boring work for you. Got a task you do every single day? I can probably make it run by itself, or add an AI to it. Here's how it works. First, you tell me what you need, and I ask questions until we agree on the job. Then I plan the tools and the flow, build it, and test it with your own data. At the end, you get something that works, with instructions. I'm based in Vietnam. I speak English and Vietnamese. I've worked in AI automation since 2021. For tools, I use Python and Next.js, n8n, Zapier and Make, Airtable and Google Sheets, and Telegram bots. One of my projects is DinexSpace, a website for making trading bots for MetaTrader 5, with 31 products on the MQL5 Market. I tested about 156 ideas on gold and currencies, and none passed. So it's still research, not a product. More on my site: AI Studio, Dutoannha, IdeaTrellis, BillCheck. I test each one before handover. Got something you want to run by itself? Send me a message on the site. Oh, and this video and voice are made with AI. Talk soon.

Services I take on

APPROACH

01

Understand

Pin down the real process and the result you need.

02

Build

Assemble the flow, integrate the tools and add the AI logic.

03

Deliver

Test it and hand over a version you can use.

Services

NHM takes on four kinds of work: workflow automation, AI and LLM integration, agents and bots, and AI tools and products.

Workflow automation

Connect manual steps across email, spreadsheets, forms and internal tools into one flow that runs on its own.

Example problem: Copy data from emails or forms into a spreadsheet, then send a scheduled report.

View details

Tools I work with

I pick tools to fit the problem and the systems you already use, rather than forcing one platform.

Automation platforms

  • Zapier
  • Make
  • n8n

Data and internal apps

  • Airtable
  • Google Sheets / Apps Script
  • Notion API

Bots and integrations

  • Telegram and Discord bots
  • Webhooks and REST APIs

AI and browser automation

  • OpenAI / Claude API
  • Playwright (only on sites that allow it)

Websites

  • SEO and GEO
  • Structured data (schema)

I design and build on these tools to a written spec, test on your sample data before handover, and list what was and was not tested. For any other tool, I say up front whether I can take it on.

EXPERIMENTS

Experiments and research

Experiments of my own, including the results that did not turn out as hoped.

  • Research

    Testing macro indicators for gold

    The MacroLens project tests macro indicators with pre-registration, placebo runs and a locked holdout. As of 08/11/2026: 160 tests, 0 passed; no indicator has been shown to have an edge. The value is the honest validation method, not a trading signal.

  • Engineering

    A tested building-block library for EAs

    A set of technically tested code blocks used to assemble EAs, with boundary-value checks: 209 checks, 0 failures (from internal test logs, 08/11/2026).
