Demhat Yoldaş

Software developer with hands-on experience building web applications using .NET, PHP, and JavaScript. I actively use AI-assisted coding tools (Claude, ChatGPT, GitHub Copilot) to accelerate development — combining AI-generated suggestions with test-driven verification and clear reasoning. I enjoy learning in the open, collaborating on code reviews, and shipping reliable, well-tested features. Seeking to grow in a product-minded, remote-first engineering team.
