Remote · IIO Subsystem
- Develop and submit C patches for the IIO subsystem, successfully merging fixes for the ADXL345 driver into the mainline tree.
- Iterate on patches for the AD5504 driver under active review, responding directly to maintainer feedback on the kernel mailing lists.
- Selected from 600 applicants for the Spring 2026 Linux Kernel Mentorship, contributing to real-world driver development in the IIO subsystem.
Marrakesh-Safi · Youth Tech Challenge Africa
- Guided 32 students across 3 teams through a 6-month hardware prototyping program from initial concept to a final hackathon presentation.
- Taught hands-on workshops covering electronics fundamentals, sensor integration, and practical embedded system design.
- Facilitated cross-cultural problem-solving among participants from Morocco and Cameroon to ensure teams delivered functional prototypes.
Nouaceur · Backend Optimization
- Diagnosed load timeouts in an 8-thread C authorization server that limited concurrent request handling to ~2-3 simultaneous transactions.
- Replaced a bottlenecking global lock with per-thread SQL database connections and finer-grained synchronization primitives.
- Increased stable concurrent request handling to 20+ requests, eliminating client timeouts and restoring parallel processing.

Founder & Maintainer · C / OpenWrt / PlatformIO
- Built a multi-node embedded system using a TL-MR3020 router to coordinate multiple external hardware modules.
- Reduced the OpenWrt OS image to fit within a 4MB flash constraint and developed a C userspace interface for device interaction.
- Designed and implemented lightweight communication protocols over TCP and UART to enable real-time hardware control.
C++ / ESP32 / Low-level Signal Generation
- Built a TCP/IP VGA adapter on ESP32, bit-banging signals while maintaining a stable networking stack for headless systems.
- Developed a newline-terminated rendering protocol for real-time console text output over a networked interface.
- Implemented graphics primitives over a custom networking layer, optimizing the ESP32 memory footprint for concurrent tasks.
C / x86 Assembly · OS Development
- Developed a Multiboot-compliant 32-bit x86 operating system kernel from scratch using C and assembly language.
- Implemented core system software including interrupt handling (GDT/IDT), hardware drivers (PIT, RTC), and PCI device enumeration.
- Built a VGA text interface and an interactive shell, utilizing QEMU to debug and test system stability during development.
