About me

I build the backend and the infrastructure that lets AI products actually ship, and I co-found the companies around them.

I’m a Web Development student at HETIC and the co-founder of two B2B AI startups. My work sits where product ambition meets infrastructure reality: designing APIs and data models, architecting cloud systems, and building the CI/CD that lets small teams move fast without turning production into a liability.

I’m analytical and proactive by default. I enjoy learning technologies that force me to think differently, from Rust and Kubernetes to the internals of the tools I use every day. I adapt quickly to changing environments, and I care about clean, modular systems that remain understandable long after they leave the prototype stage.

Let’s build something

Co-founding, backend architecture, or infrastructure that needs to hold up. If you are working on something ambitious, I would like to hear about it.
