Casablanca, Morocco - 7:03 pm local time
I’m a full-stack developer focused on building reliable, high-performance web applications from the ground up. I work across the full development lifecycle—from structuring clean, responsive interfaces to designing efficient backend logic and scalable systems.

My core stack includes HTML/CSS, JavaScript & TypeScript, and modern frameworks such as Angular and React. On the backend and systems side, I also work with Rust, Java, and Go, which allows me to build secure, performant services and optimize applications where speed and reliability matter.

I’m especially experienced in improving existing codebases: refactoring messy logic, fixing performance bottlenecks, cleaning up layouts, and making applications easier to maintain and extend. I value readable code, clear structure, and practical documentation so projects stay healthy long after delivery.

I communicate clearly, adapt quickly to new requirements, and focus on delivering solutions that are not just functional, but stable, scalable, and ready for real users.

Steps for completing your project

After purchasing the project, send requirements so Ilyass can start the project.

Delivery time starts when Ilyass receives requirements from you.

Ilyass works on your project following the steps below.

Revisions may occur after the delivery date.

Project Review & Requirement Analysis

I review your existing Spring Boot project, understand your requirements, and confirm the scope of work. This includes checking the current code structure, API design, and database setup to ensure safe and smooth implementation.

API Extension & Implementation

I extend your Spring Boot REST API by adding the requested features or endpoints, fixing issues, and applying best practices. The changes are tested and integrated cleanly without affecting existing functionality.
