Produkte / Standards / Erfahrungen / Methoden


After working in different projects for many years in my career, especially in Oracle, MS SQL and RDBMS fields, I improved myself in Business Intelligence and supported my career by working in Dwh and Etl fields.

 I also worked with many software development methodologies and project management architectures in these projects. I worked in Scrum and Agile teams and waterfall project teams. I am also a certified Scrum Master.

 My master's degree is on Management Information Systems (MIS) and my graduation thesis is on data analysis and reporting in Hospital information systems.

Sectors I have experience in my working life are Hospital / Health HIS, Insurance, Banking / Finance, Retail, Capital markets, Telecommunication.

Working with different technologies, domains and different disciplines has given me an extremely broad perspective and the ability to think in different dimensions.

I can call myself an easy adaptable and problem solver.
