      Jun 2014 - Aug 2019
      Software Engineer

      Worked on dynamically controlling container handling equipment in a terminal. I integrated new functionality into a tightly coupled system, performed extensive refactoring, and wrote numerous procedures in Oracle.Subsequently, I transitioned to a project focused on gaining experience in distributed systems. This involved developing microservices using Java and React, applying Domain-Driven Design (DDD) principles, and utilizing Kafka for messaging. Although unfamiliar with these technologies initially, I dedicated myself to learning and studying extensively, making it a highly engaging and enriching experience.- Developed 3 cutting-edge applications for managing automated cranes at container terminals.- Reduced manual error by 40% through IoT integration.- Developed and refactored 50+ Oracle procedures, enhancing database performance by 50%, leading to a reduction in system downtime. عرض أقل
