About

What I do

Senior Software Engineer at Dassault Systèmes since 2019, after three years at IQMS, with an M.Sc. from Yıldız Technical University. I build scalable, maintainable, user-friendly systems for complex manufacturing and engineering environments: full-stack development, API integrations, and UI work in Angular, Java, C#, Delphi, ExtJS, and UniGUI. I like turning complex requirements into simple, effective solutions, and owning a product end to end.

Web platforms

Enterprise web apps in Angular, ExtJS and UniGUI, and the reusable UI component libraries behind them.

Desktop & hardware

Windows and Linux software that talks to RFID, barcode, serial and camera devices.

Native mobile

iOS and Android apps that work offline and sync when they can.

Data, reporting & QA

Relational schemas, high-volume reports, end-to-end browser tests.
