Mert Çetin - Software Engineer

TL;DR:AI engineer and full-stack software engineer focused on agent infrastructure, production products, and native macOS tools.

I build software that solves real problems. My work spans AI systems, full-stack product development, and developer tools. I care about shipping quickly without compromising reliability or maintainability.

I joined Meteksan Defence full-time in September 2026. Previously, I worked on Jotform AI in a large-scale production environment. Alongside my professional work, I build open-source tools for the AI agent ecosystem, including Coal, Research Swarm, and Ankui.

Good architecture should make the next change easier. I try to build systems that are clear to operate, safe to extend, and useful beyond the demo.
