Web development

Websites that load fast and turn visitors into customers.

Custom Next.js sites — bilingual, SEO-ready, and editable by you. Designed and built by one person, end to end.

01·What's included

Most sites look fine and convert poorly. I build fast, accessible Next.js sites with the structure search engines and customers actually reward — then hand you a CMS so you're never stuck waiting on a developer to change a price or a paragraph.

Next.js, built to convert

Hand-coded, responsive and fast — Core Web Vitals in the green, not a slow page builder.

Bilingual (PL / EN)

One site, two languages, proper hreflang and per-language URLs — built in from day one.

Editable CMS

Change copy, images and prices yourself. No monthly dev bill for small edits.

SEO & analytics ready

Clean metadata, sitemap, structured data and event tracking so you can see what works.

04·FAQ

How long does a website take?

A focused marketing site is usually 3–6 weeks from kickoff to launch, depending on page count and how ready the content is.

Can I edit the site myself afterwards?

Yes. I wire up a CMS so you can change text, images and prices without touching code or paying for every small edit.

Will it work in both Polish and English?

That's the default. Both languages get proper URLs and hreflang so each ranks on its own in search.

What does it cost?

It depends on scope — most projects land in the 5–15k range. Tell me what you need and you'll get a clear quote, no surprises.
