Open to full-time engineering roles Software & AI Engineer

From RTOS on bare metal to RAG pipelines in production.

I build backend systems, LLM-powered applications, and embedded software end-to-end. The through-line is the same at either extreme: understand the constraint, measure the thing, and ship something that holds up outside a demo.

Currently finishing a BS in Computer Engineering at Istanbul Medeniyet University, graduating in the top 3% of my class. Along the way: a peer-reviewed publication, a TÜBİTAK research grant, an open-source package on PyPI, and 2nd place nationwide in Türkiye's national cybersecurity program.
