Data and websites that actually work for your business.
I build modern websites and help businesses manage their data - from analysis and dashboards in Excel and Power BI, to websites in React and Next.js that actually bring in customers.
Proof of work, not a résumé.
Placing 2nd in the world at the MOS Excel Championship (2026) and shipping live websites for real clients are two proofs of what I actually do: I help businesses get more out of their data and perform better online - from analysis and dashboards to websites that actually bring in customers.
I'm 19, self-taught - outside of school I taught myself React, TypeScript and Python, building things: agency websites, order-management systems for restaurants, full admin dashboards for car service businesses, or hooking up a database to a login system with proper permissions. I just finished technical secondary school with a programming specialization, passing both national certification exams (INF.03, INF.04) with a perfect score.
Starting this October, I'm growing that alongside my IT degree - looking for interesting projects and collaborations to get involved in, whether that's data, a website, or something else entirely.
Started building websites independently - HTML/CSS, then React, then Python's object-oriented side to round out the backend logic.
Passed INF.03 and INF.04 certification exams (programmer technician), plus strong Matura results (Math 92%, English 97%).
One-month international placement under the Europass mobility program, working in an IT environment abroad.
Qualified for the World Championship final in the Excel category - the sole representative from Poland.
Placed 2nd in the world in the Excel (Microsoft 365 Apps) category at the final in Anaheim, California - the first Polish medalist in the event's history.
Beginning IT studies at university while looking for an internship or collaboration to keep building real projects alongside coursework.
What I actually build with.
No padded list - this is the exact stack behind every project on this page.
Frontend
Where I spend most of my time - interfaces that feel considered, not default. Every project on this page ships with this exact combination.
const stack = {ui: ["React", "TypeScript"],styling: ["Tailwind CSS"],components: ["shadcn/ui", "React Bits"],};
Backend / BaaS
Supabase for auth, database and storage - used for real in the Car Service Dashboard.
Data Analytics
A certified foundation: five-time Microsoft Excel Expert and 2nd place at the MOS World Championship 2026 in Excel. I'm extending that with Power BI and SQL to build analysis and dashboards that actually support business decisions.
Data that leads to decisions.
Two case studies showing how I build analysis and dashboards - from raw data to a clear conclusion.

I run a small web agency - ADdigital.
This isn't a side project - it's a running agency. I build complete websites for local businesses around Szczecin (restaurants, insurance agencies, car services, furniture makers) and make sure they actually bring in customers, not just look good. I handle the whole process myself, from design to deployment.
