Abdelkader Ould Hennia

I’m a backend engineer focused on building reliable, scalable web applications. I design RESTful APIs, implement business logic, and deliver clean, maintainable code that teams can confidently extend.

In freelancing work, I developed a full-stack e-commerce platform with a RESTful API for product management, shopping cart, order processing, and user authentication. I designed and optimized the MySQL schema and Eloquent ORM relationships, added request validation, and built secure authentication and authorization using Laravel Sanctum.

At Fundraise Up, I handled server-side business logic for core workflows and integrated third-party services and external APIs with reliable error handling. I also improved application performance by identifying bottlenecks, increasing query efficiency, and reducing response times, while supporting production troubleshooting through code reviews and debugging.

Across my projects, I’ve built secure, role-aware systems (admin dashboards, role-based portals, and real-time messaging) with scalable RESTful APIs, caching, rate limiting, and validated database operations. I’m passionate about solving complex backend problems, learning modern backend practices, and shipping high-quality software end to end.
