Overview

A quick view to understand who I am and what’s inside this portfolio.

I’m a 3rd-year BUT Networks & Telecommunications student. This portfolio gathers my skills, projects (SAEs), and evidence (scripts, configs, docs) as part of an assessed approach.

  • Goal: demonstrate my skills clearly and with justification.
  • Content: projects, micro-learnings, skills and contact.

Timeline

Studies, internship and apprenticeship (summary).

My education

BUT Networks & Telecommunications — cybersecurity track: hands-on skills, evidence, and reflection.

BUT Networks & Telecommunications — cybersecurity-focused track

A program mixing technical skills (networks, systems, virtualization, monitoring, automation) and transversal skills (professional communication, rigor, documentation). Each semester, I rely on projects (SAEs), internship and apprenticeship to produce evidence and explain it.

Competency-based approach

The BUT program is competency-based: I must demonstrate real-world ability (projects, configs, scripts, reports), explain my decisions, and reflect on them.

  • Concrete evidence (screens, repos, configs, docs) + rationale (context, constraints, decisions).
  • A cybersecurity posture: hardening, access control, monitoring, traceability.
  • A portfolio linking SAEs + apprenticeship + internship to show progression.

Targeted competencies

Administer a secure IS
Monitor a secure IS
Administer networks & Internet
Connect companies and users
Build N&T tools/apps

Key vocabulary (BUT R&T framework)

CE
Essential components: criteria/markers that define what is expected to perform the competency well.
AC
Critical learnings: learning outcomes validated progressively (levels/semesters) to develop the competency.
