Jeanfrancois Langlois

During my internship at in I contributed to a confidential real-time platform, working across backend development, application security, and production observability.

I took on responsibilities beyond my initial scope: hardening the platform against common attack vectors, building monitoring tooling, and working on distributed systems challenges under real production constraints. It was the kind of environment where you learn fast — because you have to.

Experienced with security monitoring and analysis using Wazuh SIEM, CrowdSec, Snort IDS/IPS, Wireshark, and Nmap. I have configured monitoring environments, analyzed network traffic, detected suspicious activities, and performed security assessments in practical lab projects.

Managed and coached groups of children and adults in Judo, developing their skills, discipline, teamwork, and physical fitness. Planned training sessions, monitored progress, and created a safe, motivating environment for all participants.
