• Lead developer at top ERP developer company with responsibility for an agile team of 5 developers, maintaining customer requests, architecting and implementing strategic goals within sprints.
• Changed the game in large projects, for customers like UNILEVER, MERCEDES, Governmental Institutions which was being lost into a 100% customer satisfaction.
• The leading developer who derived the customer satisfaction from disappointment by increasing functionality and progressively improving performance of the ERP system dramatically.
• Progressively improved performance of time-critical operations up to 1000 times by utilizing modern Algorithms and Data Structures for caching and searching, by applying advanced SQL techniques for performance & scalability, Data Analysis Tools and SQL debugging techniques to find out the root causes.
• Collaborated with business analysts, test and other development teams within Agile/SCRUM sprints by using tools such as Jira, Bitbucket, Confluence, Cucumber and Selenium.
• Mentoring juniors through code reviews and regular formal/informal trainings to develop their skills and collaboration to a level of art in programming to guarantee software quality.
• Developed World's 1st real-time live, analytical budget system by using Java, RMI, JDBC, EHCache and triggers.
• Developed super-fast, lightweight, easy to manage QMS system with core Java from scratch which does have no more than 1% effect on the throughput of the whole ERP system that controls all user activities and can flexibly inform any user/group via notification, e-mail or SMS as a RESTful API service integrated to JDBC & JPA.
• Architected a query joining core functionality in system wide for reading objects which has 1-N relation and queries details one by one at a time. It could be widely used to involve heavy objects created in the ERP system. This idea had been rejected by directors of the development teams at first. But my insistent defence and proof of the systems success changed the way we built the objects which decreased the time requirement more than 100 times. A by-product of this work was pagination query class which our framework had no such feature.
