I am a


I've done various projects related to cloud computing and most of them have been DevOps type of projects. A big chunk of these project have been on AWS, a few were on Google Cloud Platform, some others were on Azure, then there were people who wanted to setup their own private clouds using OpenStack and Vmware. I've also worked with Puppet and Ansible for setting up automation, configuration management and deployment automation scripts. Around 40% of my experience are with International customers from USA, Canada, UK, Germany and France.

Digital projects manager

Like I mentioned above, I've worked on numerous cloud computing projects of various sizes, almost all using AWS.
I started in 2011 with GC and had been working with different types of AWS services like EC2, ELB, Route53, RDS, DynamoDB etc...

I always liked challenges and different types of problems that usually come with Cloud deployments.

Some common challenges were related to networking errors during the deployment, multiple services not working because of security groups modifications or permissions issues for other services (like an ELB in thinking it's a web server and it's actually running a worker process), issues with security groups - some ports open that should not be open (funny example : an NAT instance opened core TCP ports 80/443), using an elastic IP address proxy protocol (EC2-Proxy) and so on.

I got to learn a lot during these deployments especially regarding AWS capabilities and Big Data analytics tools (like Amazon Athena).  I strongly value customer satisfaction as our primary concern and do my best to provide any help needed.

It is during these years that my math and data science techniques grew the most. They set the scenes for the years ahead as an engineer. The hard work paid off at INSA and Jiao Tong University.

  • Mathmatics, statistics, numerical computation
  • Software architecture, expert systems and knowledge representation for intelligent systems.

BTS - Maintenance informatique, électronique et télécommunications

2002 - 2005


This degree trained me for the work on the field. Mostly I learned how a system is deployed on the field. The great experiences came from the people I have met during my internship and the dept of the courses I had. Not only the teachers were competent but their teaching provided the canevas for a good understanding and troubleshooting on the filed.

J’étais en charge de la gestion de projets de migration des solutions dites “legacy” vers des solutions Cloud. L’un de mes projets consistait à migrer des boites aux lettres de Microsoft Exchange vers GSuite et d’accompagner les collaborateurs vers les nouveaux usages de ce nouvel outil. J’ai ensuite eu l’opportunité de remplacer le système antivirus et antispam Postini vers Google Message Security. J’avais aussi la charge de l’évolution du “Master Windows 7 & Master Windows 10”. Un master est un installeur automatisé permettant de transformer n’importe quel PC en un PC d’entreprise. Mon travail permettait de soulager les équipes de déploiement sur le terrain en automatisant toutes leurs actions.

  • Gestion de projets cloud.
  • Administration et migration de serveurs de messagerie, anti-spam, sécurité.
  • Evolution de produits Microsoft Windows 7 & Windows 10, zéro touch.
