Programming extensions for TYPO3
TYPO3 extensions allow the TYPO3 system to be modified and/or expanded without having to change the TYPO3 core. This means that it can be updated at any time, despite the programmed extension.
Several thousand extensions can be downloaded from TYPO3.org, but it is of course also possible to program completely new extensions or expand existing extensions so that they meet your requirements exactly.
However, the premise should be to implement as many functions as possible with the existing extensions from the repository. A sensible combination is important here.
For a Berlin-based artist, I wrote an extension that creates a separate HTML page for each image collection with individual meta tags, which are automatically written to the IPTC and EXIF data using another script and written to the individual meta tags on the TYPO3 page when uploaded.
This ultimately results in hundreds of thousands of individual web pages being generated here.
On the website mopics.eu, a photographer presents images that he takes during police and fire department operations in eastern Schleswig-Holstein, among other places. The police and fire departments use these images for their internal documentation, and daily newspapers can also access them.
Logged-in front-end users can save images from the site's news section and then download them collectively as a zip file. At the same time, a list of the packed images is sent to the site operator.

The truck spare parts dealer NTH wanted to make its (often) used spare parts available via a search function on its website. After programming the extension in TYPO3 9, I also made it compatible with TYPO3 11 at the beginning of 2022.
I implemented the search function using Ajax.
On the website DDR-Zeitzeuge.de, I created a TYPO3 extension for managing contemporary witnesses. The entries can be displayed and sorted in various lists, which then always enable an individual display of the individual addresses and a contact request via powermail.
On a website that lists vacation rentals on three Canary Islands, I programmed an additional extension for the TYPO3 system to complement the TYPO3 extension Flat Manager. Among other things, this extension enables various search options, individual display of each vacation rental, and contact requests via powermail.
Only the occupancy calendar from the original extension is still used on this website.
