Ambitious projects 🧠👩‍💻
At Appsilon you'll carry out extremely interesting projects on the edge of Data Science and Artificial Intelligence.

If you want to show our clients that impossible tasks are everyday bread for us, then we invite you to the team :)
Open Source and conferences
We believe in Open Source and we try to demonstrate it by publishing Shiny R packages.
Almost every month, members of our team perform on stages of international conferences, from Australia to Las Vegas, presenting our latest achievements in the field of Data Science and R technology.

You decide.
