Machine learning engineer · researcher · builder

I build machine learning products end to end.

I turn raw, complex data into reliable models and production systems, and I'm increasingly applying that foundation to modern AI.

About

Theory and practice have always shared a workspace.

I'm a machine learning engineer, researcher, and lifelong builder. I worked full-time throughout my bachelor's, master's, and Ph.D. programs, so education and engineering were never separate tracks. Outside of work, I'm a father of two, an enthusiastic gamer, and a homelabber who enjoys building the infrastructure behind the things my family and I use.

Now

Applied AI, local systems, and tools that make repeated work safer.

I'm exploring LLM workflows and agents through the lens of production ML: evidence, evaluation, observability, and useful boundaries.

At home, I keep evolving a NixOS and Kubernetes-based homelab that supports household services, game streaming, emulation, and hands-on infrastructure work.
