Enterprise experience, indie spirit
Since 2011 I have worked as a software and database specialist at the IT department of the Presidency of the Republic of Türkiye, National Palaces Administration. I have led systems end-to-end — from the nationwide e-ticketing and turnstile platform used across palaces and museums, to a B2B travel-agency portal, a corporate ERP, an API platform and an RFID-based heritage-artifact tracking system.
My core stack is .NET (C#, ASP.NET Core), SQL Server and Oracle, plus React Native for mobile. Education: B.Sc. Management Information Systems and B.Sc. Business Administration (Anadolu University), associate degree in Computer Programming (Ordu University).
