What I'm looking for

I am looking for a dynamic work environment that fosters growth, collaboration, and innovation, where I can leverage my skills in Java development and continue to learn from experienced professionals.

I am a passionate Java Developer with a strong foundation in backend development and a keen interest in solving complex problems. Currently, I am working at Sprinters.ai, where I develop and maintain backend services using Spring Boot, JPA, and PostgreSQL. My experience includes applying asynchronous programming and multithreading principles to create scalable fintech systems with secure API integrations. I thrive in collaborative environments and enjoy tackling diverse tasks that contribute to team goals.

Previously, I served as a Technical Instructor at Ivory Training, where I conducted training sessions on Java and C# for Saudi employees. I developed tailored training materials and provided mentorship to enhance the skills of my trainees. My internship as an Android Developer at Safwa-Tech allowed me to gain hands-on experience in mobile application development, where I implemented user interfaces and integrated APIs to improve app functionality. I am committed to continuous learning and growth in the tech industry.
