Hi, I’m Mat.

I build AI and automation for teams that are done doing it by hand.

Stop being the glue between your tools.

Every week someone on your team copies, chases, checks and re-types the same things. I build the AI agents and automations that do that part. Then I stay until they actually work.

See what I’ve shipped

Taking on a small number of projects. I read and answer every message myself.

Illustration: five tasks done by hand (a missed call, a lead lost in an inbox, copying data into a spreadsheet, emailing to find a meeting slot, remembering to follow up) become one automated pipeline, and the time spent on busywork drops to almost none.

Sound familiar?

Most busywork isn’t a people problem. It’s missing software.

  1. Problem: A lead calls while you’re busy, and nobody calls back until tomorrow.

    Fix: A voice agent picks up, asks the right questions, books the visit and passes you the hot ones.

  2. Problem: Someone spends their morning copying data between the same three tools.

    Fix: Your tools talk to each other. Data moves, gets checked, and you only hear about it when something is off.

  3. Problem: The real database is a dozen spreadsheets, and they don’t agree.

    Fix: One searchable source of truth, built from the files you already have.

    Energy broker: about 20 hours a week down to 20 minutes (owner’s estimate)

  4. Problem: The AI idea has been “next quarter” for a year.

    Fix: A working version in front of real users, then we improve what they actually use.

Proof, not promises

Things I’ve built and shipped.

Real products and client work. Each case study says what I built, and where the evidence stops.

How it works

Three steps. No 40-page proposal.

You talk to the person who builds it, from the first message to the day it runs on its own.

  1. You tell me what’s broken.

    A few lines is enough: what you do by hand, how often, and what it costs when it slips. I read it and reply myself, usually with questions.

  2. We agree on the smallest fix worth building.

    I map the workflow and cut it down to the part that pays off first. You get in writing what gets built, what “done” means and what it costs, before any code.

  3. I build it, ship it, and stay.

    You see working software along the way, not slides. It goes live on your real tools, and I maintain what I build.

Who you’d be working with

One engineer, end to end.

I’m Mat. I started out as an energy engineer, then moved into software. Since then I’ve shipped a voice-AI platform, a fintech product that has been running since 2022, client automations and a long list of tools.

I use AI coding tools every day. I still design the architecture, read every change, test the failure cases and look after what runs in production. You get the speed without the mess.

  • Co-founder and main builder of One Call Flow, a voice-AI platform in a live pilot
  • Python, TypeScript, databases, deployment: the whole stack, including the boring bits
  • Based in Madrid, working remotely across the EU. French citizen.

Hiring an AI product engineer instead? I’m open to the right fully remote role, too.

Fair questions

Before you write.

What does it cost?

It depends on what we build, so there’s no price list. Before any work starts you get a written scope with the price, so nothing is a surprise. Projects typically start around €5k.

How long until something works?

Weeks, not months. The first version is deliberately small, so you see it working on your real tools early and we decide what’s next from there.

Do I need to be technical?

No. You know the job, I know the software. I’ll ask a lot of questions and translate.

Who owns what gets built?

You do: the code, the accounts and the data. If we stop working together, it keeps running and stays yours.

What if AI isn’t the answer?

Then I’ll tell you. Sometimes the right fix is a plain script or a better spreadsheet. I’d rather build that than sell you an agent you don’t need.

The work is changing either way.

Some teams will hand their busywork to software this year. Others will keep paying people to copy and paste. Pick the one task you’d happily never do again. That’s where we start.
