Technical summary

Computer Engineering student specializing in IoT and Cybersecurity, with practical experience in Linux system administration, containerization, and infrastructure as code. Active contributor to self-hosted environments using NixOS, Docker, and Debian, including a home lab that runs its own models locally. Looking for an internship in systems administration or cybersecurity, 10 weeks to 4 months, available anywhere between 19 April and 31 August 2027.

Professional experience

  1. Research Internship, CRIStAL (2XS team)

    IRCICA • Université de Lille · Lille, France · Jun to Jul 2026

    • Removed every fork and exec of iw and ip from the wifi module of a Linux probe that detects IoT devices from 802.11 management frames, replacing them with direct nl80211 (genl) and rtnetlink calls, and added automatic wireless interface discovery.
    • Contributed to the 2XS team building reliable embedded software, targeting reduced memory footprint, energy efficiency, and security at the OS / hardware-software co-design level.
    • Applied formal-methods and OS-architecture principles to system-level tooling and kernel-level debugging.

  2. Fabmanager (Fabricarium FabLab)

    Polytech Lille · Villeneuve d'Ascq, France · Apr 2025 to Present

    • Operate and maintain the school's FabLab, managing digital-fabrication equipment: 3D printers, laser cutters, CNC, and electronics workstations.
    • Support engineering students and researchers prototyping hardware and IoT projects; oversee the electronics zone in collaboration with the Robotech club.
    • Facilitate Arts/Science collaborations and coordinate equipment bookings, safety, and open-session workflows for a maker-oriented workspace.

  3. Internship in Automation Engineering

    Valeo · Tunis, Tunisia · Jul to Aug 2023

    • Automated a sound-recognition filtering procedure on an automotive steering-wheel production line.
    • Utilized Python (Librosa) for audio analysis to improve quality-control workflows.

Selected projects

  1. Local LLM Inference on Consumer Hardware

    Since Aug 2026

    • Run open-weight models on three machines with llama.cpp, running inference on GPU and on CPU only, reachable only through a VPS.
    • A 125B mixture-of-experts model on a 12 GB card: experts split across VRAM, RAM and a 29 GB SSD lookup table. 49 tok/s decode and 997 tok/s prefill.
    • One patch on the config tree that builds all my machines wires the endpoint into three agent harnesses, so prompts, configs and weights never leave the machines.

  2. Self-Hosted Linux Server Infrastructure

    Since Jan 2026

    • Runs a headless server: Nextcloud, Jellyfin, SearXNG and Samba, with strict per-user isolation. Started on Debian in January 2026, rebuilt on NixOS in February from the same config tree.
    • No public listeners: services are reachable through a VPS only, with the firewall left closed to the WAN.
    • Secrets committed to the repository encrypted with sops.

  3. Split Keyboard, Schematic to Solder

    Jan to Jun 2026 · coursework project

    • KiCad schematic and two-layer PCB for one half of a 30-key split: 112 footprints, routed with the switch matrix on one layer and the LEDs on the other.
    • ATmega32U4 firmware in C on top of LUFA HID, with 16 RGB LEDs driven by two cascaded TLC5947 PWM controllers.

  4. Jeanne d'Hack CTF Competition

    Jan to Feb 2026

    • Participated in a team-based Capture The Flag event focusing on binary reverse engineering, web application vulnerabilities, and memory corruption exploits.
