About

Backend systems and AI applications.

Software engineer focused on backend systems, AI applications, and real-time software. I enjoy turning practical ideas into working products across APIs, computer vision, automation, and real-time user experiences.

I like building practical software that connects reliable APIs, automation, computer vision, and real-time user experiences into products that people can actually use.
