Summary

I’m Erdem, a software developer in İzmir. I studied business, then took a master’s in software engineering, and now I work between two worlds: websites and apps for people, and the software that runs machines. Since 2024 I’ve built industrial systems at Simbiosis Mechatronics; since 2021 I’ve taken freelance work. Both get the same care: fast, accessible and built to be used every day.
