Website development for businesses
I design and code fast company websites, landing pages and online stores for businesses in Poland and abroad. This very site passes the Core Web Vitals thresholds in lab tests, and I build clients’ sites the same way.
Price: from PLN 2,500 net (from PLN 3,075 gross) Full pricing
In short
I build websites for businesses: I design and code company sites, landing pages and stores in React and Next.js, with technical SEO, a mobile version and code built to meet the Core Web Vitals thresholds. A brochure site starts at PLN 2,500 net, a company site at PLN 4,500, a store at PLN 8,500. After launch I can maintain it: domain, hosting, updates.
What every project includes
Speed built for Core Web Vitals & technical SEO
I write clean code (React, Next.js) instead of heavy templates. The result: fast loading on phones, Core Web Vitals within the thresholds in pre-launch tests and solid technical SEO. You can verify it on this page.
A site that leads to contact
I design interfaces around one goal: getting the visitor to act: call, message or buy. Clear hierarchy, short paths, mobile first.
Hosting, maintenance and post-launch care
I can run the whole thing: domain, hosting, deployment, updates and further development. One point of contact, no buck-passing between vendors.

Speed and SEO without the myths
Speed helps, but it won’t replace content
Google uses Core Web Vitals in ranking, but it stresses that relevant content comes first and good page experience can help when there is lots of helpful content on a topic. So I start with the content your customers search for and treat speed as basic service: a slow site loses people before it loads, especially on phones.
Technical SEO from day one
Semantic code, structured data (schema), correct canonical URLs, a sitemap and a mobile version are part of the build from the start. Google bases AI Overviews on the same foundations, so nothing separate is needed for them.
Questions about websites
How much does a website cost?
A brochure site or landing page from PLN 2,500 net (PLN 3,075 gross), a company site from PLN 4,500 net (PLN 5,535 gross), a store or portal from PLN 8,500 net (PLN 10,455 gross). You get the exact fixed price in writing within 48 h of a free call. All prices are on the pricing page.
What technologies do you build with?
I write in React and Next.js (plus Tailwind, and a headless CMS when your team edits the content) instead of heavy templates. The result is fast loading, Core Web Vitals within the thresholds in Lighthouse tests and clean, SEO-ready code. You can check this very page in PageSpeed Insights yourself.
Do you handle hosting and maintenance too?
Yes. I can run the whole thing: domain registration, hosting, deployment, updates, backups and further development. You get one point of contact instead of buck-passing between a web vendor, a host and an IT person.
Will the site be optimized for Google (SEO)?
Yes, technically: semantic code, structured data (schema), speed, mobile and correct canonical URLs. That’s the foundation. Rankings also depend on content, competition and links from other sites, so content and ongoing SEO are quoted separately.
Do you work with clients outside Poland?
Yes. Most of my projects run remotely, for clients across Poland and abroad: day to day, phone, email and video calls are enough. Calls are in English or Polish, and in Silesia (Tychy, Katowice, Gliwice) I can also meet in person.
What should I build for you?
Tell me what you want to build or what slows you down. I usually reply the same day, within 24 h at the latest. After a free 30-minute call you get a written fixed-price quote within 48 h.
