A little about me

A bit
about me.

I build web apps and real-time systems that feel instant and hold up under load.

My work runs from restaurant ordering and ecommerce to contact centers and banking systems.

Read my résumé Open to collaboration

How I like
to work.

  1. Clarity before complexity

    Remove until the decision becomes obvious.

  2. Performance is a feature

    Measure the experience, not just the machinery.

  3. Build for the people using it

    Technology succeeds when it disappears into the task.

What I’m
focused on.

Building with Rust and exploring agentic engineering, retrieval systems, and local models.
