Hello and welcome to my website

I am Julien Jerphanion, a 24 years old French graduate mainly interested in Software and Applied Mathematics. I crave for learning new things and crafting my work.

Lately, I graduated from the MSc. Applied Maths, Computer Vision, and Machine Learning of École Normale Supérieure Paris-Saclay.

I now work as a freelancer to solve problems in those domains, I also give private lessons and training in mathematics, computer science, software and data science.

As a free and/or open-source software user, I sporadically contribute to some of them to give back, to learn and to better address new problems.



I sometimes write posts about various subjects on my blog, including — but non-restricted to — software and mathematics.

Academic Curriculum

MSc. Applied Maths, Computer Vision, Machine Learning, Sep. 2019 - Nov. 2020

École Normale Supérieure Paris-Saclay, France

During this year I’ve learned a lot about various topics at the intersection of mathematics and computer science.

I was particularly interested in topics such as computational statistics, optimisation, and kernel methods from their theoretical principals to their implementation.

Some courses:

Visiting Student, Aug. 2018 - Dec. 2018

National University of Singapore, Singapore

I had the chance to study as a visiting student at NUS during my curriculum at the Université de Technologie de Compiègne.

Courses work:

MSc. Computer Science, Sep. 2014 - Jun. 2019

Université de Technologie de Compiègne, France

The Université de Technologie de Compiègne is kind of a special university in France.

There, I’ve studied applied mathematics, computer science and engineering, languages and humanities.

The last two years focused on a data analysis course work. I also got two minors: one in mathematical modeling and another in philosophy of technology.

Some projects I worked on

I am in the process of documenting them here. As of now, if you want to have a better overview of open projects I worked on, you can explore my GitHub profile.

About the way I work

I think technology and frameworks are just means to technically solve problems and I do I think most problems first exist because of misknowledge, misunderstanding and/or miscommunication.

I thus try every day to become a bit more knowledgeable, a bit more understanding, and a bit more communicative. I then try to technically solve problems.

In that later case, I like to come up with simple, efficient and effective solutions which can be understood and properly maintained on the long term. In this process, I do not hesitate to propose and to learn about new subjects.


I am mostly confortable working with:
