My road
The world sells templates.I build what works.

I've walked every one of these roads myself. That's why I know how to build yours.
How I work
You know where things stand at every step. No disappearing for a month.

Real businesses, shown with their permission.

A warm site in Dutch and Polish: booking is one tap away, and Katie edits her own texts and prices in the G.O.T panel.
Concept builds
Concept builds — a look at how I build sites: cinematic, fast, each with live video. Click and step inside.
Who's behind it
One person. From sketch to launch.
My name is Jacek. I design and build every site myself — you talk to the person who writes the code, not to a sales team. Based in Rotterdam, working in Polish, Dutch and English.

Questions
A landing or one-pager ships in 24–72 hours, a larger site or app in 7–10 days. You get a firm date before I start — not “someday”.
Yes, fully. Domain, hosting and source code are yours. I don't lock you in — if you ever move on, you take everything with you.
I use modern hosting (Vercel) — fast and with no surprise invoices. The first support period is included; after that we agree on ongoing care or I hand you full control.
Of course. Revisions within the agreed scope are included, and larger changes are quoted separately — you always know the cost before any work starts.
Yes — in the G.O.T panel. You log in with a link sent to your email (no password needed) and update the text and photos yourself, in every language on your site. The preview shows each change instantly, and it goes live about a minute after you publish. You can't accidentally break the layout or colours, and any field can be reset to the original in one click. You'll start with a guided tour and a step-by-step guide.
Yes — PL, EN and NL with correct SEO (hreflang, per-language meta). Foreign-language copy is checked for natural fluency, not run through a machine translator.
No. I help with content, and I can generate graphics and video for your brand. We start with whatever you have.
Aetheron
Every darkness you step into, I've already walked through.
There's always a backdoor. My job is to find it and build a way through where others see only a wall. I do the same with your project.
Let's talk
I've built the bridge.Now it's your move.
A site, a store or a system — each one starts with a single conversation. Tell me about your project — I'll reply within 24 hours.
