Here are some of the projects I have worked on in the past:
Doctolib for hospitals
My team works 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).
