Software Producer

Direct contract work on existing projects for meo-media, a print house based near Oldenburg. I was also involved in developing a new product, a white-label shop. Each project team has different in-house and external staff. All projects use PHP and Laravel. Some use VUE 3.x, and one also uses Inertia.

I am currently finishing modification and extension work on several web applications for this client. Before that, from September to December 2020, I expanded the intranet/backoffice solution with automated delivery of a customer-specific DIN/VDE standards reference work. In some cases this includes historical or withdrawn standards and drafts—up to over 18,000 PDF documents. These documents receive a customer-specific stamp on each page, plus usually PDF password protection and usage restrictions to protect them from changes as much as possible.

Reimplementation of a website that I had developed between 2000 and 2019, with numerous interim extensions, now featuring a full back‐office area for capturing orders of many different types for large clients, special one‐off orders, and document distribution in a distributor‐style system. The user base includes in‐house staff as well as external users (VDE Association) and seminar speakers running seminars on behalf of the client.

It includes a variety of features, for example:

• Sending emails to authorized users with a unique access link. Sent in batches by order type at set times, but also triggerable manually at any time. It can even be sent separately for individual recipients. Sent to customer groups and/or individual customers.
• Manual entry of orders as well as automatic order generation. The auto-generated orders can be manually edited if needed.
• Automated sending of reminder notifications to users who are late in retrieving.
• Automated cleanup tasks to conserve server resources.

In the reimplementation, Laravel Livewire is used extensively, greatly simplifying the previously very complex AJAX implementation.

Freelance work, 100% remote, on a project for event management in the security sector. It’s a combined server and client application with a single codebase that switches behavior via configuration. My tasks included implementing the client and syncing event data and ID scans between server and client using Windows services written in PHP.

I was able to significantly expand my knowledge of Laravel and VUE on this demanding project. The work included OAuth2 authentication for personal users and app clients via Laravel Passport, storing documents in a virtual database‐filesystem with a folder structure similar to Explorer/Finder. I created VUE components for displaying folders and files with thumbnails. Installing and uninstalling PHP/Laravel synchronization services in the Windows Service Manager using php_win32service was also part of my role.

Dictation service over the internet. Assigning remote workers to dictation orders with medical and legal focus. Includes client order entry with dictation and template upload, automatic and semi-automatic assignment of remote workers (individuals and groups), status tracking, and automatic notifications to relevant recipients. The complete 2014 reimplementation as a web application with a JSON API replaced the XML web service (PHP) and Windows applications (Delphi) solution I had used from 2005 to 2014.
