Apprentice Computer & DevOps Engineer
LinkedIn Github Kaggle Keybase Mail Phone

I am a young developer & an engineering student, and you are welcome to my web-portfolio.

I currently work as an apprentice DevOps engineer & Scala developer at the Orange company. I have the opportunity to work with DevOps tools such as Jenkins, Travis, Scala SBT, Docker, Ansible, and also to learn how the application performance management works in the Orange's Application Performance Experts team.

I am highly motivated by the Big Data in general, and about technologies such as Machine learning, etc. I am constantly learning (by myself, or at school) about these subjects, and I definitely want to go further and study in that field after being graduated at ENSSAT. Let me know if you are interested in my profile for a potential internship in this domain!

You will find on this website some information about me, my skills, and about some of my projects.
