About

I’m Leo.
Call me yll0rd.

An AI/ML engineer with a full-stack background. Mostly self-taught, always learning.

I build software and explore machine learning. Here, I’m making space to share both the work and the person behind it.

My path

I started with full-stack development, building web applications and working across the frontend and backend. That work led me to integrate LLM-powered features into real products.

My focus now is on training and deploying machine learning models end to end. I’m still learning, building, and figuring out where I want to take that work next.

Beyond work

Away from code, I enjoy playing acoustic guitar and reading manga 📖. They’re part of my life that I want to make room for here, too.

My writing will also include personal observations, questions about life, and whatever else stays on my mind.
