About Me

I'm a Senior Software Developer with over 5 years of experience building robust systems in the .NET ecosystem and crafting AI-driven solutions that make a real difference.

At Turna.com, I've helped build and scale a travel platform that serves over 100,000 daily users -- integrating flight and bus providers, leading framework migrations, and automating deployment pipelines across 10+ microservices.

Beyond backend development, I'm deeply interested in AI and machine learning. I've worked on prompt engineering, AI agents, and contributed to research on speech synthesis using deep learning architectures. Currently pursuing my Master's in Artificial Intelligence.

I speak 6 languages and have studied and worked across Turkey and Lithuania, giving me a global perspective on problem-solving and collaboration.
