Senior Software Developer/ Consultant
In Germany there are hundreds of community colleges (?VHS?) which are
offering courses at their facilities and online. The problem is that there is a lack of
transparency on what courses are offered overall, since each community college has its own
website, offering and advertising their program strictly on a local level. We identified the
need of a website that would serve as a central registry for those courses, offering a fast and
uncomplicated geo-based search and categorization of the catalog.

LightRoom - Joomla Bridge (LR-Connect)

Full Stack (Project Lead)
Within the Foto-Community there was a need to publish edited photos directly
from LightRoom to the photographers website. The idea was to implement an extension for
an existing CMS system that would enable displaying the photo collections put together in
LightRoom in a flexible and simply integratable way.
Subsequently a Joomla component extension was developed that implemented an API
which enabled the secure sync between LightRoom and the photographers Joomla website.
There are prebuilt components that can be dynamically added to content pages, embedding
synced photos from the uploaded LightRoom collections.

The client already ran a website built with wordpress that offered ad-based

customer payout management. Since the platform was already live and in use, the decision
was made to implement a custom Wordpress Extension to accomodate all needed features.

?Syncomatic? Distributed File Sync

Several workflows of the customer required the exchange of files with external
service providers. This file exchange (sync) should follow strict workflow bound rulesets
making conventional file-sync solutions not an option. A distributed file sync solution was
developed that would allow the integration of all required workflow related state
management and triggers/hooks for each of the file states.

Description: Working in the foreign language field comes with a number of special needs in
terms of territory planning. A software was developed that would not store data on the cloud,
but encrypted on the local machine. It allowed to create and manage territories, assign them
to publishers and to print out pretty maps to work with in the field ministry. Due to changes in
legislation this software is not in use anymore.

End To End Testing for the MMP Project

Full Stack (Project Lead), Dev-Ops
There was insufficient test coverage on several workflows and UNIT testing was
hard to implement due to the code design of those software components. The solution was
to build solid E2E tests in CI that would guarantee that new features would not break existing
workflows. To accomplish this a database seeder had to be implemented that would allow
for static test data, while being flexible enough to be easily updated during development. A
CLI tool was implemented that allowed for fine grained data snapshotting, and a CI workflow
was created that would run Cypress on a production like environment on every commit.

The customer needed a better way of comparing images from photo-shootings
side by side. To be completely integrated into their existing workflow, this needed to be done
within the existing Digital Asset Management software that the client used at that time. A
modern SPA JavaScript web-app was developed that allowed for detailed sorting and
comparison of fotos, offering side-by-side views of multiple pictures, with zoom and
highlight options.

Refactoring of the MMP Project

The project depends on various third party dependencies that need to be
configured and installed on the web-server it runs on. To make local development more
feasible the project was refactored in order to be containerized. In that effort, various
JavaScript libraries got replaced, PHP code got ported to the newest version of the
language. Following that the whole CI/CD pipeline was overhauled, which allowed for a more
fluid user testing workflow and more transparent deployment workflows.
