Websites and shopsthat bring incustomers.
I'm Mateusz Kornaś. For 18 years I've built websites, shops and apps — first for banks and pharma companies, now for businesses like yours. You talk to me, and I design it, build it and keep it running. No middlemen, no jargon.
First call is free · I usually reply the same day · a fixed price before we start
One price, agreed before we start.
Every project is quoted on its own, because scope makes the biggest difference. After a free 30-minute call you get one number in writing — no surcharges along the way, no obligation.
Built for clients.
Restaurant · Customer site
Their first commission-free sales channel. Every order placed on the site stays 100% with the restaurant — and so does the customer.
Jeweller · E-commerce
An online brand that finally looks like 145 years of craft — with a shop where every piece is one of a kind.
Construction · Corporate site
A showcase worthy of 15 years in the market — a site that builds credibility with private, corporate and public investors on its own.
Eighteen years is the short version.
Banking, pharma, lottery, high-traffic retail — industries where breaking isn't an option. That's where I learned to build for uptime, audits and scale, not just for the demo.

A complete digital presence.
Instead of a web studio, an app shop, a sysadmin and an AI consultant — one person and one conversation.

Not only websites for small businesses.
The same 18 years also work for agencies, for businesses covered by accessibility law, and for restaurants. Each of these has its own page.
Products and courses I run myself.
I run my own products and courses, so I know what keeping something alive online really costs — and I design so it still works two years from now.
Before you write.
How much does a website cost?
It depends mostly on the number of pages and features (shop, bookings, integrations) and whether the content already exists. So there is no one-size price list: after a free 30-minute call you get one fixed figure in writing — no surcharges along the way. If the budget is tight, I'll say what fits within it, or that a smaller first step makes more sense.
How long does it take?
A landing page usually takes 2–3 weeks, a company site or shop 4–6 weeks, an app 8–16 weeks. You see progress on a test version every week, so nothing surprises you at the end.
Will I be able to edit the content myself?
Yes, if you need to. I then build the site on a CMS where you change text, photos and blog posts yourself. If you'd rather not deal with it, I build a lighter site with no admin panel and make the changes for you.
What happens after launch?
Fixes are included for the first two months (a 60- or 90-day warranty, depending on the package). After that you can stay on a flat-fee care plan: updates, backups, monitoring and small changes.
Do you work with businesses outside your city?
Yes. I work remotely with businesses across Poland and abroad, in Polish and English. We talk online or by phone, and you follow progress in your browser.
Project on your desk?
Two sentences about what you need is enough. I usually reply the same day.
