Web application development in Dortmund
A website presents information. An application does work — it holds state, enforces rules, and produces something at the end. Most businesses that need the second one are running it on a spreadsheet nobody is allowed to sort, and paying for that in errors rather than in software. For Dortmund businesses, quoted in EUR from $200, typically live in 10 days.
What web application development includes for a Dortmund business
Fixed scope, agreed in writing before development starts. From $200, typically live in 10 days.
- Specification covering user roles, permissions and every state a record can legitimately be in
- Relational schema designed first, with constraints enforced in the database rather than hoped for in the code
- Authentication with hashed credentials, session handling and role-based access control
- The application itself: forms, lists, filters, actions and the reporting that justified building it
- Transactional email sent through your own authenticated domain
- Audit trail on anything that changes money or status
- Deployment, environment configuration and a backup procedure verified by an actual restore
- 30 days of snag fixes after go-live

Why this matters for Germany specifically
German law requires a compliant Impressum and Widerrufsbelehrung, and getting them wrong invites an Abmahnung — a formal cease-and-desist with costs attached. On German builds these are structural requirements, not footer decoration.
Why Dortmund sites are built to be edited by you
A site you cannot update is a site that decays. Prices go stale, staff leave, the opening hours are wrong for six months. So the parts of a Dortmund build that change often — text, images, prices, opening hours, team members — are editable by you without touching code or paying me.
That is a design decision with a cost: it takes longer to build an editable block than a hard-coded one. It is worth it because the alternative is a maintenance dependency that benefits me and not you, and a developer whose income depends on you being unable to change your own opening hours is not aligned with your interests.
Healthcare and clinics in Dortmund
Clinics carry a compliance weight most businesses do not. Appointment forms collect health information, which is a special category under EU GDPR, and it cannot be emailed to a generic inbox or written to a plain-text log. That constraint has to shape the build rather than be bolted onto it afterwards.
Beyond compliance the deciding factor is reassurance: practitioner names, registrations a patient can verify, honest pricing, and what actually happens at a first appointment. Anxiety is why people delay booking, and a site that reduces it outperforms one that merely looks modern.
The contact form that silently fails
The most expensive bug on a small business website makes no noise at all. A form posts, shows a thank-you message, and the email never arrives — usually because the host's mail function is unauthenticated and the receiving server drops it without a bounce. The business concludes demand fell.
The fix is authenticated SMTP with SPF, DKIM and DMARC configured on the sending domain, plus a database write so a submission survives even when delivery fails. If you are unsure whether your Dortmund site has this problem, submit your own form from a phone on mobile data and see what actually arrives.
What I am not claiming about Dortmund
- I have no office, postal address or phone number in Dortmund
- I cannot meet you in person, and if that is a requirement you should hire locally
- I am not claiming existing clients in Dortmund 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
Web application development in Dortmund — common questions
- Do you provide ongoing maintenance after launch?
- Thirty days of snag fixes are included after launch at no extra cost — anything that does not work as specified gets fixed. Beyond that there are monthly plans for updates, backups, monitoring and small changes. They are optional and cancellable; a site handed over properly does not require a retainer to keep running.
- Will the site actually rank in Dortmund search results?
- The build handles what is technically controllable: crawlable HTML, correct headings, structured data, fast pages, a clean sitemap and Search Console set up on day one. Ranking also depends on your competitors, your domain's age and the links pointing at you, which no developer controls. Anyone guaranteeing a position is guessing or lying.
- What happens if I am not happy with the result?
- Work is delivered in milestones against a written scope, and you review each one on a staging URL before it is paid for. If the delivered milestone does not match the scope, it gets corrected before anything moves forward. That structure exists so disagreement is resolved at the stage it happens rather than at the end when it is expensive.
- Do you build on WordPress or something custom?
- Whichever the project justifies. WordPress when you need to edit content constantly and want a familiar admin. A static build when speed and security matter more than a plugin ecosystem. Custom PHP and MySQL when the logic is genuinely yours. The choice is explained in the quote with its trade-offs, not presented as a foregone conclusion.
- Can you migrate my Dortmund site without losing rankings?
- Yes, and the redirect map is the whole job. Every existing URL is mapped to its new equivalent with a 301 before launch, and anything with no equivalent goes to the closest relevant page rather than the homepage. Sites lose rankings in migration because that mapping was skipped, not because migration is inherently risky.
- Do I need to provide the content and images?
- Content, yes — you know your business and I do not. I will restructure and edit what you send so it reads for the web, and I will tell you where a section is missing. Photography is worth paying a local photographer for; stock images of people in offices are recognisable as stock and quietly cost you credibility.
- Do you actually work with businesses in Dortmund?
- Yes, remotely. I work with German clients from Islamabad, quoting in EUR and invoicing in EUR. I have no office, address or phone number in Dortmund and will not pretend otherwise. If your project needs someone physically present, hire locally — I will say so in the first reply rather than after a deposit.
