A Programmer's Success Story
In 2003, Huta Warszawa took an unexpected step by securing my contract with Mostostal for what was then an astronomical amount—equivalent to today’s 100 million PLN.
At the time, all of this was happening behind my back. Once I understood the situation, it became clear to me that I had been handed a challenge that would change the course of my career.
At first glance (sight), Huta Warszawa’s decision seemed risky—the factory stood to lose the entire deposit if I failed to deliver the program upon which their success depended.
Where Was the Logic Behind this Venture?
The answer lay in the unpaid invoices owed to "Huta Warszawa", which hung over Mostostal like an unintended burden.
Mostostal, a prestigious company, was leveraging other people’s money to build its potential.
They paid minimal amounts, akin to installment plans stretched over many years—even accepting penalty fees, as it was still far more advantageous than paying Huta in full.
So, what kind (amount) of money was Huta Warszawa fighting for? Most likely, no less than 500 million PLN.
Why Did Huta Warszawa Take Such a Huge Risk?
I was a programmer with no prior experience—in fact, the situation was becoming increasingly unfavorable for Huta. At Mostostal, there was immense pressure to have the program developed; there was no doubt about that.
The problem, however, was that no one wanted to write the program for Mostostal—or rather, no one knew how to. All fifty software companies that Mostostal approached had declined the project.
Could It Be a Hidden Collusion Over the Contract?
Probably not, and for several reasons—one of which is the timing and context: the years 1998–2003. Collusion schemes became a societal phenomenon after 2005, arriving a bit late for the turn of the millennium.
To clarify, the ten largest software companies in Poland—the giants
of Polish IT—responded unequivocally:
"The technological process described in the Mostostal contract contains such intricate and complex mathematical mechanisms that it is impossible to program."
To any internal voice suggesting, "This is just standard negotiation procedure," I respond directly: "Not on this scale, and not at that time."
While there is some support for the "internal voice" theory—namely, the fact that each of the software companies Mostostal approached suggested a non-refundable advance payment ranging from 500,000 PLN to 5 million PLN (depending on the company) "to try" developing the program—this approach does not align with collusion but rather with a lack of confidence in the feasibility of the project.
A Third Party
This was not a Mostostal employee, but someone whose own professional matters were unfolding at the time. For this person, fairness in the contract’s valuation was more important than for anyone else. In fact, I am 100% certain that this person wanted me to get the most challenging contract of my life—but also to 100% ensure that I would never be able to complete it.
This outcome was meant to be decided by the expert opinions of mathematicians, who were tasked by the companies to evaluate, analyze, and assess the problem. Their findings were documented on official records.
I will say this much: everyone at Mostostal was well aware that the companies refusing to take on the project were acting honestly and transparently in their approach.
What Does This Knowledge Bring to "Huta Warszawa"? Simply Put—Trouble.
This creates a significant risk for Huta Warszawa. If Mostostal strikes a deal with the largest software company and gives them the equivalent of 50 million PLN today "to try to write the program," it could turn into a never-ending "financial odyssey."
In such a scenario, Huta might never recover (get back) its 500 million PLN, as the funds could be endlessly consumed by unsuccessful attempts to develop the program.
From "Minus Zero" to Success
When I started working on the program, I wasn’t just at a "zero" level as someone with no professional experience—I was at a "minus zero" level, influenced by a group of outstanding mathematicians who had declared,
"This cannot be done."
The preparations began in September 2003. Over the following months, I met with Mostostal’s technologists and IT specialists, learning about production processes, supply mechanisms, and the operational details of the plant. This was an intense training period that allowed me to understand the problem and envision potential solutions.
The key moment came in December during a presentation of my vision for the program to Mostostal’s board. In the room were 15–20 people: directors, managers, and production plant supervisors. Despite the stress and technical difficulties during the presentation, made me earn their trust. The head of the board stood up and said:
"Marek, you have the green light from all of us. You’re writing this program."
The Outcome of My Work
The program I created was successfully implemented at Mostostal, enabling "Huta Warszawa" to recover 500 million PLN in lost capital. This was an immense source of satisfaction—a testament to the fact that even someone without professional experience, armed with determination and a willingness to expand their knowledge, can tackle challenges that others deem impossible.
The saying "you can’t pour from an empty cup" proves true, yet behind my effort was a wealth of knowledge that simply went unrecognized.
My approach to the contract was met with both admiration and deep skepticism. Just a year earlier, I had applied for a position as a technologist in a subsidiary or office branch of Mostostal, with strong backing. At the time, the job offered a six-month salary of 6,000 PLN net. Now, the same Mostostal wanted to sign a six-month contract for 60,000 PLN—a situation that felt almost unreal.
Despite the surreal nature of the offer, I approached the contract professionally, making an effort to bury any lingering skepticism deep in my pocket.
Summary
My story is an example of how courage, risk-taking, and collaboration can lead to groundbreaking achievements.
At that moment, Mostostal and Huta Warszawa placed their trust in someone who, on the surface, seemed to have no chance.
Yet, we managed to accomplish something that became a lasting part of the history of these companies—and my career.
"A Man Who Brings Hope for a Better Tomorrow"
This was the title of an award I received in 1999 as an MZA Warszawa bus driver on the Inflancka "R-5" line. It was given to me by Huta Warszawa as a token of gratitude for my commitment to the workers on their night shifts.
- My role went beyond driving I ensured their comfort during the commute from the Huta bus loop to the office building.
- To provide a peaceful atmosphere, I avoided opening the rear doors at certain stops, preventing the cold air or noise from disturbing their rest.
- Once we reached the loop, I allowed the workers to nap on the bus for a good 40 minutes while I had my dinner in the MZA dispatcher’s office.

"A Man Who Brings Hope for a Better Tomorrow"
Description of the Award
The award I received from the workers of Huta Warszawa held great symbolic and practical significance, impacting the lives of many. It was a token of gratitude for my daily efforts in transporting Huta employees to their night shifts on bus lines 156 and 195. Thanks to my dedication, the workers could comfortably reach the Huta office building, ensuring a peaceful start to their "demanding workdays"
The award also had an academic dimension and was accompanied by a modest bonus of 200 PLN, deposited into the R-5 depot’s fund. This gesture coincided with dramatic changes in public transportation – during the "low-floor bus reform," as many as 100 of the best drivers and 10 mechanics were unfairly dismissed from the R-5 depot.
My efforts, including working over 110 hours driving a bus with non-functional brakes on route 107, contributed to the reinstatement of these individuals. The drivers, who were unjustly dismissed, found themselves in a state of deep mental agony – nearly in a hopeless professional situation. Decision-makers in the executive committee had put them in this position through resolutions and directives that, instead of offering support, only exacerbated their struggles. Despite the harsh conditions, further tragedies were averted, and the day of “ultimate downfall” never came.
The Gesture of the Still Workers
The workers, taking advantage of moments of rest and sleep on my bus, appreciated my efforts. While they rested, I would have my dinner in the dispatch room, and this entire gesture was immortalized in a letter of gratitude sent to the Director of R-5. Upon reading their words, the director was visibly moved. However, among other drivers, there were warnings that my actions might lead to disciplinary consequences.
Low-Floor Buses – Overcoming Challenges
As a student working in public transportation, I was assigned to operate special, new low-floor buses. Unfortunately, these vehicles suffered from significant design and maintenance flaws, often ending their routes on tow trucks. Among 700 drivers, I was the only one who could operate these buses for more than a few hours.
My efforts during this challenging time, both for MZA and Huta Warszawa, were recognized, and the award I received symbolizes a combination of courage, determination, and collaboration under difficult circumstances.
In one year of work, I achieved 150% of the standard working hours, which allowed me to sustain the operations of the drivers and mechanics who found themselves in the mental agony of their lives. During this time, 100 drivers and 10 mechanics were dismissed from their jobs. Their fortunes only changed when the Executive Committee, invited by the dismissed workers to the R5 depot, began analyzing my yearly work schedule. Based on this, a temporary reinstatement of the dismissed employees was enforced. However, their continued employment depended on my ability to maintain 110% of the working hours standard.
These were not easy days—brakes were malfunctioning, and the clutch and brake pedals would cause unexpected reactions, such as electric shocks. The financial penalties imposed on me for working with that bus were far greater than one could imagine.
The most absurd penalties were for a "lack of lights" in the bus—even at noon. The total sum of these penalties exceeded fifty times the average fines imposed on other drivers. This raised controversy and a kind of awakening among the drivers, who couldn’t believe I was actually working with that bus.
After I completed the period of 110%+ hours, the full reinstatement of drivers and mechanics had to take place. A second Executive Committee meeting was convened, this time with three times as many participants as the first meeting. Surprisingly, many attendees came armed, postponing their arrival several times. There were far fewer drivers present compared to the first meeting, as this second session was supposed to focus only on formalities.
I was also meant to attend the meeting as a witness to my work, but due to the procedures and the excessive financial penalties, I was unable to participate. Everything proceeded in accordance with the rules and regulations, albeit through a different process.
It was only the intervention of the steelworkers—about whom no one knew anything—that changed the course of events. Even the best intelligence network in the world, available to the Executive Committee and connected to a former President of Poland, uncovered nothing extraordinary about the five-person delegation from the steel mill. This delegation, however, reacted emotionally to any mention of me. They sobbed discreetly and knelt on the steps of the bus I was driving, praying inside when the other drivers weren’t looking.
These were people full of humility and respect for hard work, giving everything of themselves so that others could receive much more than they could ever give to themselves. Nothing about these overworked, weathered, and perhaps slightly dirty workers stood out to the Executive Committee. Yet, their unyielding character and strength, harder than the steel they produced, lay hidden deep within them. They did not flaunt their courage or determination.
The steelworkers’ persistence ultimately led the Director of ZTM to annul the absurd penalties imposed on me for my exemplary and model work. Furthermore, at the steelworkers' request, one of the ZTM directors took on the burden of paying off those fines by taking out a personal loan—a sum equivalent to the value of five apartments in Warsaw.
