Building a bridge between data, finance, and real-world impact for Poland
I come from a village of 70 residents in Poland's Kuyavian-Pomeranian region. From there, I built my path through Gdańsk University of Technology and CERN, toward an opportunity I once saw as out of reach: admission to MIT.
Today I work at CERN, where analytics, reporting, stakeholder management, and business value meet. My trajectory is increasingly clear: from data and analytics into finance, and from technical delivery into broader leadership. After the MIT Master of Finance, I want to return to Poland and help make finance, data, and AI more practical for students, professionals, and smaller institutions.
Admissions story
I received offers from MIT, Imperial College London, and Columbia University in 2025, but financial constraints prevented me from enrolling. In 2026, I was admitted to the same three institutions again, reinforcing the consistency of that trajectory.

Vision
After MIT, I want to make finance, data, and AI more practical in Poland
I want to return to Poland with stronger financial training and international operating experience, then apply both where they can be most useful: in better financial decision-making, stronger data literacy, and more accessible technology for smaller organizations. The ambition is not abstract innovation, but practical capability where it is still unevenly distributed.
Financial education
Help students and young professionals build practical fluency in personal finance, investing, and decision-making.
From ideas to action
Encourage young people to use data, technology, and financial thinking to build projects, careers, and businesses with real economic value.
AI for smaller organizations
Help smaller firms and local institutions adopt useful AI tools that improve efficiency, access, and decision-making.

Why back this path
What I am building goes beyond one degree. It is a long-term path at the intersection of data, finance, leadership, and public impact, shaped by demanding environments and ready for the next level.
Built through results
I grew up in a village of 70 residents in northern Poland and built my path step by step through consistent academic and professional results. That path led from Gdańsk University of Technology to CERN, and later to repeated admission offers from MIT, Imperial, and Columbia. This trajectory is already backed by execution, discipline, and results.
Why this moment matters
I have already turned opportunity into measurable outcomes: analytical work used by thousands of users, collaboration across complex stakeholder environments, and mentoring initiatives reaching hundreds of people. Support at this stage would accelerate a profile that is already creating value and is ready to scale its impact further.
A focused direction
My goal is to build strong practical expertise in finance and data and apply it where it creates tangible value. MIT would strengthen my financial toolkit, expand my network, and deepen the international exposure needed to operate across institutions, sectors, and borders.
Value beyond one career
What I build rarely stays limited to my own advancement. Through mentoring, public speaking, and community work, I usually turn personal opportunity into something shared. Backing this path means supporting someone likely to transfer knowledge, open doors for others, and create impact beyond one career.
