About

As a goal-directed, result-oriented professional with a strong background in information technology, I have over 15 years of experience in computer programming, problem-solving, and client relations. I hold a Master’s degree in Computer Engineering from Ahmet Yesevi University and a Bachelor’s degree in Computer Engineering from Doğuş University. Throughout my career, I have demonstrated high energy, initiative, and focus, enabling me to identify issues and develop innovative solutions effectively. My areas of strength include intrapreneurship, adaptability, and training, which have been instrumental in my professional growth and contributions to various projects. In my current role at Infolojik, I serve as a Senior DWH BI Developer and BI Project Manager, where I focus on Oracle 12c reporting, developing ODI 12c mappings, and managing data assets. I also perform the Scrum Master role and utilize PowerBI. My previous freelance roles involved business intelligence consulting for companies like Fibabanka, Brisa, and MacFit, where I handled data modeling, report building, and Oracle PL/SQL programming. At Bankalararası Kart Merkezi, I worked as a Business Intelligence Engineer, analyzing vast amounts of data to support various departments and projects such as the Enterprise Workflow & Document Management System and OWB to ODI 12c Migration Project. My experience also includes roles at Mirsis Bilgi Teknolojileri, Yapı Kredi Sigorta, Migros, Eti Pazarlama, and Kuşman Technology, where I contributed to a variety of data warehousing, business intelligence, and software development projects.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
