H. Gözde Akgün
I have worked with Serdar as my team member more than one year. First he was a key user to the application that we are developing, then he joined my team as a business intelligence specialist. He is very eager to learn. He improved him self technically with his self-disciplined and hard-working. If he has a task/job to complete, be sure that he will complete it. His communication with the peers (co-workers, managers and suppliers) are effective and clear. Hope to work together again.

Sep 2020 - Dec 2021
In this role, I was responsible for designing and implementing data warehousing solutions that enabled the client to better manage their vast amounts of data, streamline their business processes and make informed decisions based on actionable insights. The energy industry is constantly evolving and I was fortunate to work with some of the latest technologies in data warehousing and business intelligence. This gave me exposure to cutting-edge tools and methodologies that I could apply to other projects in the future. During the course of the project, I worked closely with cross-functional teams to gather requirements, design data models and develop ETL workflows that extracted, transformed and loaded data from various sources into the data warehouse. I also created custom reports and dashboards using the one of the industry-leading BI tool, OBIEE, to help the client visualize their data and identify trends and patterns. In brief, I took a part of the projects of Izmir Natural Gas Inc. & Esgaz Natural Gas Inc. ● Data warehouse modeling and administration ● Developing data integration flows with ODI ● Working with Oracle Business Intelligence solutions (OBIEE-OAS) ● Developing reports and dashboards ● Using mostly Oracle SQL - PL/SQL and experienced in other languages Show less
