About

I studied computer science at West University of Timișoara, with a focus on web development and machine learning. Since then I’ve been shipping software that people use every day.

At VAEV Research and Development Agency in Vienna I built and maintained more than ten web platforms for EU-funded research projects. On my own I built Corevuo, a multi-tenant project management platform with 48 data models behind it, and PlainMail, an email hosting service where I run the mail server myself.

Before that, as a machine learning intern, I raised a handwriting recognition model’s accuracy by 20%. I still like the parts of a system most people avoid: DNS records, background queues, permission models.

I speak Arabic (native), English (C1) and Turkish (B1–B2).
