Trainings & R-Shiny Apps

From clutter to ... a clear vision

Many data problems are actually quite simple,
just the solutions may seem overly complex.

This is what DataScience-Apps is about
empowering people to harness the concepts of data science and use them in their everyday life.

From source code to documentations, the deliverables ensure that your projects are scalable, reusable, replicable, and adapted to both general and technical audiences:


Shiny Apps are always interactive and fully functional along with embedded educational material.


The R Code is optimally structured and commented for other data scientists to reuse.


Rmarkdown files detail the whole process, step by step. I also provide ppt presentations or other type of content in plain English.


Handovers & Trainings go beyond a simple project completion. It empowers all the teams to use, understand and scale the project when needed.
