About Yassine

I am a Full Stack Developer with over 4 years of experience in designing and developing modern web applications using .NET (C#) and Angular.
I focus on creating robust, scalable, and maintainable solutions, applying principles of clean architecture, well-structured APIs, as well as solid DevOps and automated testing workflows.

I have worked on various projects, ranging from automated product configuration tools in the refrigeration sector, to secure microservice-based web platforms, and SaaS HRIS solutions.

Naturally curious and driven by code quality, I enjoy transforming complex challenges into simple, efficient, and elegant solutions.
