Booking and scheduling systems, Stripe-based payments, Telegram messaging and automation, and custom backend solutions. I connect existing tools so the process runs without manual work. A separate article covers when automation is worth it.

Yes, on a monthly retainer for several clients, from €45 (HUF 15,000). It covers updates, backups, bug fixes and smaller changes. If I handle the hosting and the domain as well, their cost sits inside that fee — running the site costs you nothing on top. I also take over existing sites, including ones I did not build — in that case the first step is a survey. A separate article covers what this means in practice.

More people now ask a language model for a recommendation instead of browsing a results page. The model quotes specific passages from source pages. AI visibility is the work that gets a business into the search indexes the models answer from, and makes its content quotable: clean hierarchy, self-contained answers, the same details everywhere. This is also what the site's main article is about.

There are fixed package prices, each with what it includes written down. A website: one page €330 (HUF 120,000), up to five pages €530 (HUF 190,000), with parts you edit yourself €800 (HUF 290,000). A system: online payments with invoices €530 (HUF 190,000), a paid Telegram channel €800 (HUF 290,000). Care runs on a monthly fee that includes hosting and the domain: €45 (HUF 15,000) for a simple site, €70 (HUF 25,000) for WordPress, €100 (HUF 35,000) with payments or bookings. Prices are final, invoiced under the small-business VAT exemption: in forints in Hungary, in euros elsewhere in the EU. For what does not fit a package, you get an itemised quote after the first, free assessment.

Because it stays in one pair of hands, and in practice that means two things. First, there's no project manager and no handover between developers — what we agree on is what I build, so there's nowhere for the information to get lost. Second, the result is personally my reference: not a team's output with my name washed out of it. The price shows the difference too, because there's no office rent or sales layer behind me. In exchange, one person's capacity is finite: I don't take on more than I can do properly.

There is. If an existing site runs on a system I don't know — not WordPress and not plain HTML — I won't take it over for maintenance. An unfamiliar system is handled efficiently by whoever built it: they know the decisions that aren't visible in the code. In that case I offer one thing, and I say it plainly: rebuilding the site in WordPress or plain HTML. If that isn't worth it for you, I'll say that too.

By email. You describe what you want to solve, I ask questions, then send a quote. After the first exchange we usually talk as well — in a video meeting. It is easier to get to know each other that way, and it builds trust on both sides: you see who you are trusting your system to, and I understand better what you need. Most of the work stays in email though, and that is deliberate: it keeps the project clearer for both of us, and nothing rests on improvisation — we hold the same written record, readable any time.
