Here are some of the projects I have worked on in the past:
Babbel B2B
My team works on the B2B part of Babbel. We're working on features enabling companies to provide language courses to their employees.
Doctolib for hospitals
My team worked on making Doctolib better for hospitals. This includes adapting existing features so that they work at a very large scale, and creating completely new ones.
Comparison services
At lesfurets, I worked in a team creating comparators for home/financial products such as energy, broadband and mortgages.
AMCS
I developed an Adobe Reader plugin for AMCS, an application used at the TU Dresden to make lectures more interactive.
VeRecipes
An easy way to find new vegatarian recipes. I developed a REST API with Spring, deployed it to AWS and made an Android application to consume it.
Adnosco
I helped develop new features for Adnosco, a research project about privacy. I specifically focused on improving the UI.
ParkenDD
I helped overhaul the UI of ParkenDD (not yet deployed in the real application).
