About

Thirty years of building things that had to work

I am not a consultant who read about business. I have built and run several of my own, the largest a multimillion dollar supplements company, and I wrote the software that kept them running.

The short version

I have been the client

I have spent more than thirty years in software, and more than twenty five years running businesses that lived or died by it.

I have founded and run several companies, and AI Solutions Guru is one of them. The largest is Muscle Nutrition, a multimillion dollar ecommerce business selling nutritional supplements, which I built and scaled across Europe and the United States. I did not hire an agency to build the platform. I built it myself. The site, the integrations, the databases, the servers it ran on, the marketing that filled it and the analytics that told me what was actually working. When something went down at two in the morning, I was the one who fixed it.

That is the difference between me and most people selling AI right now.

I have been the client. I have signed the invoices, carried the payroll, chased the supplier who did not deliver, and watched a campaign quietly burn money for a week before I caught it. I know exactly what it costs when technology fails, because for a long time it was my money on the line.

Why that matters to you

You are buying judgment, not software

You are not really buying software. You are buying somebody's judgment about what to build and, just as importantly, what to leave alone.

There is a lot of AI on the market right now that will impress your friends and do nothing for your revenue. I am not interested in selling you that. I would rather find the two or three things in your business that eat your week, automate those properly, and leave the rest of your operation alone.

I have been around the block. I have seen most of the practical problems a business can run into, and I know which of them technology actually solves and which ones it quietly makes worse. I am not naive about it and I am not impressed by my own tools. I am pragmatic, I am stubborn about things working, and I know what it takes to keep a company running day after day.

What I bring

Three things most agencies cannot

Thirty years in software

Java, PHP, Python, databases, Linux server administration, network administration, and scaling hardware and software to carry real traffic. Full stack, from the metal upward. I do not outsource the hard parts.

Companies I actually ran

Founder and CEO of Muscle Nutrition, a multimillion dollar supplements business across Europe and the United States, and of AI Solutions Guru. Sourcing, logistics, payments, customer service, growth and everything that breaks in between.

Two markets, two languages

Fluent in English and Italian. I have sold in both and I understand how differently they buy, how differently they negotiate, and how differently they trust.

I have travelled five continents, Europe, Asia, Africa and the Americas, and it taught me that no two markets, businesses or people buy the same way, so I do not walk into your business assuming it works like the last one I saw.

What I do now

I put that experience to work

I put that experience to work for other businesses.

  • AI agents and automationsystems that answer, qualify and follow up without you touching them
  • Integrations and full stack platformsyour tools finally talking to each other
  • Digital marketing and SEOvisibility that compounds instead of stopping when the budget stops
  • CRM and business developmenta pipeline that runs on structure, not on memory
  • IT consultingan honest read on what to build, what to buy and what to ignore

How I work

How I work

1

Revenue first

Every project starts with the same question. What does this actually earn you or save you. If I cannot answer it, we do not build it.

2

Plain language, always

You will never get a document from me full of terms designed to make you feel behind. If I cannot explain it to you clearly, I do not understand it well enough yet.

3

You own what I build

No lock in, no hostage situations. Your systems, your data, your accounts. I want you to stay because it works, not because leaving is painful.

4

I will tell you no

If AI is the wrong answer for your problem, I will say so on the first call and I will tell you what to do instead. That has cost me projects. It has also earned me clients who came back three years later.

Let us talk about your actual problem

Not a pitch, not a demo. A conversation about what is slowing your business down and whether technology is genuinely the right way to fix it. The first call is free and you will leave it with something useful either way.
