Web applications. Systems underneath.
I'm Ayoub, a developer based in Morocco. I build web applications and spend time understanding what sits underneath them: servers, databases, and operating systems. Some of my work is practical, some is for learning. I try to be clear about what works, what is unfinished, and what I learned along the way.

Role: Socket.IO Chat, WAF/ModSecurity, Protection Logic & CI/CD
A full-stack rental platform built collaboratively. My focus centered on developing the real-time communication service with Socket.IO, hardening the perimeter with WAF and ModSecurity rules, implementing request protection logic, and managing automated testing pipelines via GitHub Actions.
Role: Technical Setup, Core Data Fetching & Solution Brainstorming
An automated reconciliation system being developed in collaboration with a Morocco-based business owner. The goal is to compare food and goods served at counters against point-of-sale cashier records to calculate daily served totals and flag audit discrepancies.
Role: Full-Stack Application Ownership
A complete HR certification exam preparation platform (SHRM-CP/SCP & HRCI / PHR) featuring structured modules, timed exam simulations, spaced-repetition flashcards, private document synthesis, and Pip—an AI study coach powered by Google Gemini.
Projects focused on POSIX primitives, event multiplexing, database storage layout, and Unix process lifecycles.
Role: Sole Creator & Systems Researcher
An educational SQL database engine built to demystify internals: parsing SQL syntax, serializing records into fixed-size storage pages, navigating slotted pages, and traversing B-tree / B+ tree index structures.
Role: Co-developer (42 Curriculum)
A high-performance HTTP/1.1 server developed from scratch in C++ using nonblocking sockets and multiplexed I/O. Handles continuous client connections, HTTP request parsing, CGI execution pipelines, file uploads, and configurable virtual hosts without blocking the process.
System administration project orchestrating a secure multi-service infrastructure. Configured Nginx with TLSv1.2/1.3, WordPress via PHP-FPM, and MariaDB on isolated Docker networks with dedicated volumes using Alpine Linux containers.
3D raycasting maze engine inspired by Wolfenstein 3D, written in C. Implements Digital Differential Analysis (DDA) raycasting, wall texture projections, sprite positioning, and boundary collision physics.
Unix shell written in C replicating Bash behavior. Features lexical command tokenization, syntax validation, pipeline orchestration (`|`), file redirections (`<`, `>`, `>>`, `<<`), environment variable expansion, and built-in commands.
I am a software developer based in Morocco. I studied at 1337, part of the international 42 Network. The peer-to-peer curriculum immersed me in C, Unix systems programming, POSIX network protocols, memory management, and building fundamental tools from scratch without third-party frameworks.
Alongside systems programming, I build complete modern web applications. I care deeply about understanding the full path of an execution: how a user action in a browser translates into an HTTP packet, how a socket server polls for events without blocking, how storage engines lay out records into fixed-size pages on disk, and how to protect applications with sound security architecture.
My goal is to write software that is honest, fast, and maintainable. When a project is in progress or experimental, I document its exact boundaries rather than claiming unsupported benchmarks or inflated production statistics.
