Custom AI

I sell the part you can measure. Not the part you cannot.

None of my AI work has ever run in a customer's product. I am saying that here rather than waiting for you to ask it after a deposit. What I sell is one narrow job that runs, handed over with its numbers — including when those numbers are “it did not work well”.

First: if you want to BUY a chatbot, this is the wrong page

A number of search terms lead people here, and most of them do not need what I do. If you want a sales chatbot, a document-scanning tool, or an AI product you can switch on this week — go and buy one. That is SaaS vendors' work, they do it far better than I will, and they charge a monthly price a small business can carry.

Names like MISA, Nhanh.vn, Base.vn or Ahachat in Vietnam, and Chatfuel internationally, are the right answer for that need. They have a product, they have a price, they are live in an afternoon. I do not compete there and I am not going to stand in front of you claiming I would do it better.

This page is for a different question entirely: “we have one specific process, our own data, and nothing off the shelf fits — is there a way, and how accurate is it actually?”

Where my AI work actually is

Three lines, with no rounding:

  1. Yes

    An MSc in Computer Science with an AI focus — machine learning, natural language processing and computer vision — from Can Tho University. Eight years of software development before that, mostly TypeScript and systems that actually run.

  2. Not yet

    None of my AI work runs in a customer's product today. The machine-learning side is applied research in progress, and I am moving it from coursework toward real work. I will not sell you a list of AI customers, because that list does not exist yet.

  3. So what I am selling

    Integration, measurement and operation. Putting a model into your actual process, measuring how right it is on your actual data, measuring what each run costs, then handing it over so you operate it. Not a pre-trained model, not fine-tuning a foundation model, not AI strategy with no build attached.

Why selling the measurement is the better sale

This is not a nice line to cover for missing experience. It is the technical reason: an AI feature with no numbers attached is an assertion, and an assertion you cannot check is not checkable until the day it runs wrong on your data.

  • Accuracy only means something on your data

    An accuracy figure measured on somebody else's dataset does not transfer to yours — different industry, different way of writing, different noise. I build the evaluation set from your own samples, run it before handover, and report that number.

  • Cost per answer is not a constant

    It depends on the real length of your sentences, how many calls you make a day, and what the model costs on the day it runs. I count on your own sentences rather than estimating from intuition — and I write the assumptions into the quote.

  • “It did not reach the bar” is a valid result

    If the evaluation set comes out low, you should know that before you order the next package. A two-week measurement that answers the question is cheaper than a six-month build that reveals it was never going to work.

What I can honestly do

These two are the parts of my machine-learning work I have reason to believe in, and both rest on one thing: the Vietnamese text of a Vietnamese business.

  • Extracting Vietnamese documents

    Contracts, invoices, handover minutes, stock notes — documents with a familiar shape scattered across half a dozen places. I do the part that reads them and lands them in a fixed schema, so the data can be used afterwards instead of re-read every time.

  • Normalising Vietnamese text into one schema

    The same fact written four different ways is a defect waiting to happen, not a style preference. Getting it into one schema — and keeping it there after handover — is the actual work.

2 weeks · measured on your own data

Two weeks. It ends in a set of numbers on your own data — accuracy, cost per run, and what it gets wrong. Not a build.

Questions about AI

Have you shipped AI for a client?
Not in productised form. My machine-learning work is applied research in progress — an MSc with an ML/NLP/CV focus — and I am actively moving it from coursework into real work. I have no AI client list to put on this page and I will not invent one. That is exactly why the first package is a measurement rather than a build.
Where should I start?
With a measurement, not a project. The entry package is roughly two weeks and ends with numbers on your own data: accuracy, cost per run, and what the system gets wrong. You pay for the measurement before committing to anything further.
What will it cost per month to run?
I will not give you a number from the sky. It depends on your real sentence lengths, your daily call volume and the model's price on the day it runs — so I count on your own sentences and write the assumptions into the quote. Every AI quote I produce carries an estimated run cost line.
Does my data get sent anywhere?
No. I do not use your data to train somebody else's model, including my own. That is a boundary I write into the scope, and I think it belongs in writing.
Do you do computer vision — product quality inspection from images?
I do not sell it as a service. Image inspection needs a conveyor, controlled lighting and a real volume of defect images in the plant — which a small business here usually does not have. I describe that as a capability, not something you can order.
Will this automate everything?
No, and I do not promise it will. At the scale of a small business, most of the time goes into data that disagrees with itself rather than into the model — a process where you cannot produce clean data will produce poor results, however good the model is.

Related pages

This page is not the whole offer. Most of the work I do arrives as an internal system first, with AI appearing somewhere inside it — or not appearing at all, in which case I say so.

Describe a process you do by hand and the outcome you need. I will say plainly whether AI is the right tool for it — and if it is not, I will say that too. The first conversation is online, carries no consulting fee, and does not require you to travel anywhere.
