What the certificate states
It was issued by Developer Akademie GmbH, an AZAV-accredited training provider, in February 2025, with a web applications focus. The document lists backend development, REST APIs, database design and deployment as competencies, and Python, Django, PostgreSQL, SQL, Redis, Linux, Docker and cloud as technologies. It exists as a PDF and can be viewed on this page.
When a website needs a backend
Many do not. A site that explains your offer and leads to a phone call works without one — and is faster and cheaper to run that way. A backend is needed as soon as your website has to remember something: appointments that are taken. Enquiries that have a status. Customer data that should still be correct tomorrow. Drawing that line honestly is the first backend decision, and it usually saves you the most money.
What it changes during the build
A data model that reflects how your business actually works, rather than a form someone bends into shape later. Interfaces that let your website talk to your point of sale, your calendar or your accounting without anyone retyping numbers. And storage locations chosen on purpose: enquiry data does not sit in the public web directory, it sits where a visitor cannot reach it.
How you can check it on this site
The appointment system on this site is not a bought-in calendar service, it is built in-house: free slots, request, confirmation email with a calendar entry and a cancellation link — on our own servers, without your data passing through someone else's booking portal.
What this means for your project
- Your data lives in a structure that fits your business — not one that happened to fall out of a form.
- Existing systems are connected instead of maintained twice.
- Enquiries and bookings are validated on the server, not only in the sender's browser.
- Whatever is stored sits outside the publicly reachable directory.
