Who am I?

Hello, and thanks for asking! My name is Julien Dessaux and Adyxax is my nickname. I am a 37 years old guy working in IT.

Professional Career

alter way

alter way is a web hosting company.

I joined alter way in October 2016 for a more technical role and a bit of a career shift towards networking and infrastructure. There I had the opportunity to rework many core systems and processes that helped the company grow in many ways.

On the networking side I helped put in production and operate our anti-ddos systems and reworked then maintained our bgp configurations for that purpose. I also lead the upgrade project of our core network to 100G and implemented a virtualized pre-production of all the core devices. This allowed the industrialization of the configuration management by implementing a custom tool for generating and deploying the configurations.

I also maintained and improved the way we operate our netapp storage clusters by automating processes and standardizing configurations. This allowed to rework the way we operate our PRA to reduce downtimes and allow for proper testing of the PRA before we need it. The backup solution was then redesigned from the ground up to fit the scale and workloads of alter way. On a final note I had the opportunity to work on the redesign of how we deploy and operate alter way’s public cloud offering (networking, storage and compute).

It has been a great and diversified experience.


Intersec is a software company in the telecommunication sector.

I joined Intersec as a trainee in April 2009, then as the company’s first full time system administrator in September 2009. At the time Intersec was a startup of just about 15 people. When I left in June 2016 it had grown up to more than 112 people with branch offices in three countries, and I am glad I was along for the ride.

Intersec gave me the opportunity of working as the head of IT for about 5 years (not counting the first year and a half when I was learning the ropes), participating in Intersec’s growth by scaling the infrastructure, deploying new services (Remote access, self hosted email, backups, monitoring, wifi, etc.), recruiting and then managing my team (2 people for many years, 3 the last year). I also designed the high availability platforms we deployed Intersec’s products on.

I left Intersec looking for new challenges and for a new life away from the capital. Paris is one of the best cities on earth, but I needed a change and left for Lyon.


I graduated with a master’s degree in computer science from the ISIMA, an engineering school in France.

Prior to that I obtained with honours a Baccalaureate S option Mathematics (A-levels equivalent), then went on to study for competitive admission into French engineering colleges in Classes Préparatoires in Mathematics and Physics (MPSI/MP).

I am a French native speaker and consider myself fluent in English (I scored 920 at the TOEIC test). I have a pre-intermediate level in Spanish.

Online presence

I have an activity pub account at @adyxax@adyxax.org (a mastodon compatible self hosted instance). I also have a Linkedin account that I do not use.

I maintain this website to showcase some of my works and interests. You can also look at my personal git server or my github which mirrors most of my repositories. I can usually be found on oftc or libera IRC servers.

Other interests

When I am not doing all the above, I like running, biking, hiking, skiing and reading.
