After working at Thales, I worked at the French Ministère des Armées (Ministry of Defense) on several applied research topics. In team of three to four people, I made significant theoretical and practical contributions that directly impacted operational successes.
Along with the team, we strived to industrialize more and more of our codebase (C, Python), and bring up a micro-service based architecture.
This transition was a fascinating time. When I arrived, we were using Subversion and VMs; two years later, GitLab, CI/CD, docker, Kubernetes, code quality metrics, monitoring, efficient logging, …
Novel ideas we pushed forward at the time were NLP and neural networks applied to our field, as well as new finite automata implementations. As a team, we trained on those topics and gained significant expertise.
