Java Backend Developer specializing in Spring Boot, Spring Security, and REST API design — with hands-on experience in C# and ASP.NET. I build secure, scalable backend systems backed by PostgreSQL, MySQL, and MongoDB, containerized with Docker and managed on Linux. On the frontend, I complement my skills with Angular.

I design and ship clean REST APIs with JWT authentication, Spring Data JPA, and proper separation of concerns — deployed via Docker on Linux environments. I version everything with Git, test with Postman, and have experience with CI/CD pipelines. Beyond backend, I enjoy crafting Angular frontends with modern patterns like signal-based state management.

Originally from Syria, I hold a Bachelor's degree in Civil Engineering from the University of Damascus. After relocating to Austria, I transitioned into software development through programs at Everyone Codes and 42 Vienna, where I developed strong skills in Java, Spring Boot, and modern development practices.

I thrive in multicultural, agile teams and am always eager to learn new technologies. My background gives me unique perspectives on problem-solving and adaptability.
