Sobre mí
I'm Bartek, a web developer based in Poland.
I build websites for small businesses by hand — no WordPress, no page
builders. The result is a site that loads almost instantly, scores full
marks in Google's PageSpeed tests, and that the owner can actually edit
without calling anyone.
I care about two things: that the site is fast, and that you own it
completely. Domain, hosting and source files go to you.
I work in English and Polish, Central European Time.

Kadrownia — my own web studio. I design and build websites for small businesses by hand: semantic HTML5, CSS3 and vanilla JavaScript. No WordPress, no page builders, no frameworks and no build step — which is why the sites load in a fraction of a second and have nothing that needs updating. What each project includes: - Full technical SEO: unique metadata, Schema.org structured data, sitemaps, canonical tags, and hreflang where the site runs in more than one language - Accessibility to WCAG AA: contrast ratios, focus states, semantic markup and keyboard navigation - Performance work: WebP conversion, responsive images, self-hosted fonts for GDPR compliance - Deployment and infrastructure: Netlify, DNS on Cloudflare, SSL, and business email with MX, SPF, DKIM and DMARC records - Written instructions and a screen recording, so the owner can edit the texts without calling a developer I also build custom interactive features from scratch — price calculators, service configurators, before-and-after sliders and quote baskets. Every project I ship scores 100 out of 100 in all four Google Lighthouse categories. Clients keep full ownership: the domain and hosting go on their own account and they receive the source files.

B-Art M Studio — my own photography business. Event, portrait and business photography across the Warsaw region: parties, concerts, individual sessions and commercial shoots on location. Over 400 completed events and sessions, with a 5.0 rating on Facebook. I handle the whole job myself — briefing the client, shooting, full post- production, colour grading and delivery in web-optimised formats. I also built and maintain the studio's website: bilingual Polish and English, with a categorised portfolio, a price list, an article journal for clients and a booking form. It was the first site I built, and it is still the one that brings in the studio's enquiries.
