The code on the back seat leads here.

I hope the ride is going smoothly.

And since you are here: at night I write my own software.

My name is Marcin. By day I drive people around Radom, in Poland. In the evening I sit down at a laptop and build things nobody asked me for.

It started in the Netherlands, in June 2025. I was working twelve-hour shifts in a warehouse, coming back to my room and writing a program on an old laptop, meant to watch over a computer and stop it slowing down for no reason. I did it because I wanted to know how. There was no plan, no company, and nobody waiting for it.

A year later that same program passed review and went into the Microsoft Store. The same file that was written at night, between shifts.

There was a gap in the code. For three weeks I was driving long-haul across Europe with nothing on me but a phone. I did not stop planning or writing, I just did it from a cab instead of a desk. The change history does not show that part.

Nothing much has changed since then except the scale. There is work in the day and code at night. I did try selling once, I even had a small online shop, but marketing patter turned out not to be for me. I would rather build a tool that genuinely helps somebody and give it away.

So I am not selling you anything here. Below you can simply see what came of it.

27releases of the program, from 1.0.0 in October 2025

Every one of these numbers can be checked in the public change history.

PC Workman

A Windows program: temperatures, fans, startup entries and whatever is slowing the machine down. It is in the Microsoft Store. Free.

Dashboard. Processor, graphics and memory live. The assistant inside runs offline.
Cooling. A fan curve, a temperature target, and the RPM you can watch respond.
Startup manager in PC Workman
Startup. What launches with Windows, and what is safe to switch off.
In-game overlay. FPS and temperatures in the corner, in a layout you pick yourself.
Open PC Workman → The program's page, the download and the full list of changes.

Scaling Laws

A game about running an artificial intelligence lab from 2022 onward. Being built now, at night. Already available to download.

Server room. You buy cabinets, stand them on the floor and watch the heat.
Research board. Nothing is instant here - research takes time.
Designing a model. How many people your cluster will hold, before you spend a penny.
Offices and people. Rented floors, your company name over the door, and who sits where.
Open Scaling Laws → The game's page, what it is, and the download.

Two I am not showing yet

GuideAI, a guides service - sign-in works, payments do not yet. And Baka Bake Bakery, a small Unity game. I would rather not send anyone to something that does not work.

The whole story

Read the story → Longer, with dates: four jobs in two countries, a warehouse, the Microsoft Store, and what has still not come of it. The shop that no longer exists → A shorter chapter: what I was doing before the program existed, and why one of those projects left no trace.

If you want to chip in

The program is free and will stay free, and the game can be downloaded at no cost today. Putting it on Steam, though, means paying the publisher fee once, and that is what I am raising.

Where else I am

Everything in one place X GitHub LinkedIn

Marcin Firmuga, HCK Labs, Radom, Poland. If you want to talk about any of it in the car, go ahead. I like telling the story.
