About

Java backend engineer with 5+ years of experience building secure, scalable systems across banking and telecom domains. I specialize in designing and developing microservice-based architectures, REST APIs, and cloud-enabled backend platforms using Java, Spring Boot, and Oracle databases, with a strong focus on performance, reliability, and clean design. I’ve worked on enterprise-grade banking solutions for global clients like National Bank of Egypt and ADCB, as well as high-scale telecom systems where optimization and stability are critical. My work has helped reduce processing timelines from days to hours and improve system efficiency at scale. I value clarity in design, maintainable code, and systems that hold up under real-world load. I enjoy working closely with product, QA, and DevOps teams to ship backend systems that are robust, compliant, and production-ready.
