Web developer in Rotterdam

Businesses in Rotterdam usually come to me after a site has already been built once and disappointed. That is a useful starting point, because it means the requirements are no longer theoretical — you know exactly which parts failed. Rebuilding from a list of specific complaints produces a far better result than rebuilding from a mood board.

One thing worth knowing about building for Netherlands

iDEAL accounts for the majority of Dutch online payments. A Netherlands store that leads with card fields and buries iDEAL is losing conversions at the last step for no reason other than build order.

The performance budget every Rotterdam build is held to

Pages are built to a hard weight limit rather than optimised afterwards, because retrofitting speed onto a heavy site is several times the work of not making it heavy. In practice that means no framework runtime on a content page, fonts subset to the characters actually used, and images generated at the sizes actually displayed.

For Netherlands specifically this is a commercial number, not a vanity one. A visitor on mobile data who waits four seconds is frequently a visitor who is gone, and the analytics will record it as a bounce rather than as the lost sale it was. Core Web Vitals is simply the name Google gave to noticing this.

Manufacturing, wholesale and B2B in Rotterdam

A B2B site in Rotterdam serves two audiences with opposite needs. A buyer wants specifications, tolerances, lead times and a downloadable datasheet. A procurement officer wants your company registration, insurance, certifications and payment terms. Serving both from one undifferentiated "About" page serves neither of them.

The highest-value feature is almost always a searchable product or capability index carrying real part numbers, because that is what engineers search for. It is unglamorous, it is a database problem rather than a design problem, and it produces enquiries that arrive already qualified.

Images shipped at ten times the size they display

A hero photograph exported at 4000 pixels wide and displayed at 400 is the most common single cause of a slow page. The browser downloads all of it and then discards most of it. On a phone over mobile data that is several seconds spent waiting for pixels nobody will ever see.

The fix is generating each image at the sizes actually used, serving AVIF or WebP with a fallback, and setting explicit width and height so the layout does not jump while they load. It is mechanical work with a directly measurable result, which makes it the first thing worth doing on almost any Rotterdam site.

Hiring a developer who is not in Rotterdam

The question worth asking a remote supplier is not "where are you" but "what happens if you vanish". My answer is the handover: the repository, the hosting and the domain are in your name from the first week, not the last. Any competent developer in Rotterdam could take over the project mid-build without calling me, and that is the only guarantee that means anything at this distance.

What I am not claiming about Rotterdam

A location page is the easiest place on a website to imply something untrue, so here is the other side of it plainly:

• I have no office, postal address or phone number in Rotterdam
• I cannot meet you in person, and if that is a requirement you should hire locally
• I am not claiming existing clients in Rotterdam specifically — my live work is listed on the work page and you can check it
• Nothing on this page is a guarantee of search rankings, which no developer can honestly offer

Rotterdam web development — common questions

What hours will you be available to us in Rotterdam?

My working day lands at 06:00–15:00 in your time, which is roughly 6 hours inside a normal Rotterdam working day. In practice you can raise something in the morning and have it answered the same morning, and a scheduled call is easy to place at a civilised hour for both of us.

Can you fix my existing site rather than rebuild it?

Often, yes, and it is usually the cheaper answer. Speed problems, a broken mobile layout, a form that silently fails or missing structured data are all fixable on the site you already have. I will tell you which of the two you need after looking, and a rebuild only gets recommended when the fix would cost more than starting again.

What payment methods can my Rotterdam checkout accept?

For Netherlands: iDEAL above all else, plus Mollie, Stripe and SEPA. The right combination depends on your average basket and your customers, and picking wrong is expensive — the payment method a buyer expects but cannot find is one of the most common reasons a checkout is abandoned at the final step.

How long does a Rotterdam project actually take?

Three days for a business site, seven for a store, ten for a custom application. That holds because the process is fixed rather than improvised and because your content exists on day one. What stretches a build is almost never the code — it is waiting for copy, logos and photographs, so those are requested before the clock starts.

Who owns the website when it is finished?

You do, completely. The domain is registered in your name, hosting sits in your account, the code lives in a repository you control, and any payment provider account is opened in your business name. Credentials are handed to you as they are created rather than at the end, so you are never locked out of your own site.

How do you handle our customers' data under EU GDPR?

Your customer data is governed by the EU GDPR, supervised by the Autoriteit Persoonsgegevens, and sending it to a developer in Pakistan is a restricted transfer. That is resolved by a DPA incorporating the EU Standard Contractual Clauses, published on this site and pre-signed before you send an enquiry — not drafted after you ask about it.

How much does a website cost in Rotterdam?

A business website starts from €75 and goes live in about three days. An e-commerce build starts from €140 in around seven days, and a custom application from €180 in ten. Those are starting figures — the exact number is fixed in writing once scope is agreed, and it does not move after that.

Where this page sits

This page covers Rotterdam. Every other town in Netherlands is listed on the Netherlands coverage page, and the full worldwide list is at all locations.

Before you enquire: pricing is published rather than quoted on request, how I work covers the process end to end, the work page lists live client sites you can open, and vendor information answers the procurement questions.
